Options générales
Validation (using regular expressions) (preg_validation)
Description
This option lets you specify a regular expression with which you can validate all the parts of a question.
If any question or subquestion value does not meet the validation requirements, the background colour of the text entry field will be changed to red so that users can easily see which parts of the question need to be corrected. Thus, you can do on-page validation. In this way you will not need to wait for the user to click on the submit button to validate the respective question.
Valid values
- Any valid regular expression
Example

Affichage
Label column width (label_column_width)
Description
The label column width option allows you to set the width of the label/subquestion (of the wrapper of each label). Please note that this option does not set the width of the column where the labels are located.
Available options
- Default: If selected, a default value will be allocated to have both the label and its corresponding text input box on the same line. For example, if the text input box width is 92% and the label column width is set to default, the label and its corresponding answer text box will be displayed on the same row. If the width of the label "wrapper" was higher than 7%, then the text input box would be displayed on the next line.
- Hidden: If chosen, the first column (that contains subquestions) will not be displayed to the survey respondent.
- 8%; 17% ... 92%; 100%: the bigger the selected value, the larger the width of the subquestion.
Example: If you wish to have each subquestion displayed on its own row, increase the width to 100%, the text input box being then displayed under each subquestion.
Hide tip (hide_tip)
Description
Most questions will usually include a tip that says "Please choose one of the following options" or a hint text on how to fill out the question. This attribute allows you to turn off or on this tips/hints.
These tips/hints include validation criteria messages (such as min/max number of answers, min/max/equals sum value). If hide_tip is enabled, these messages will be hidden. However, if the user enters invalid data, the tips will appear. They will be coloured in red, getting changed to green once the validation criteria are met.
Available options
- On - the tips/hints are hidden;
- Off (default).
Input box width (text_input_width)
Description
This attribute sets the width of the text input boxes (of the "wrapper" of the text input boxes). The input box is used to introduce an answer to the (sub)question. If the value of the width is sufficiently high, then the text input box will be displayed on the next line. Please note that this option does not set the size of the input or the width of the entire column!
Available options
- Default: If selected, a default value will be allocated to this attribute in such a way to have both the label and its corresponding text input box on the same line. For example, if the text input box width is 41%, the value of the width of the text input box will be a value that allows both the label and the input box on the same line (58% in this case). If the width of text input box was higher than 58%, then the text input box would be displayed on the next line.
- 8%; 17%...92%, 100%: the bigger the selected value, the larger the width of the text input box.
Example
- If you wish to have the input part displayed below the subquestion/label, select the 100% option from the dropdown list.
Random answer order (random_order)
Description
Deprecated for Answer Options : As of 5.5.0, this attribute is not longer used for ordering answer options. Please see QS:Answer_order
This attribute causes LimeSurvey to ignore the existing order of answer options/subquestions, and instead it orders them randomly. This option permits the survey creator to diminish the survey bias. Please note that if a question has subquestions, the order of subquestions will be randomized, not the order of the answer options.
Available options
- Yes - Randomize when participant enters survey
- No (default)
Text input box size (input_box_size)
Hint: This features is available starting in version 3.0.0
Description
This function allows you to set the size of the text area (the text input box). By default, LimeSurvey forces the input box to be displayed with a default size. This can be overridden by making use of this function.
To move the box on the next line, you need to increase the size of the wrapper. To do so, increase the value of the text input width attribute.Valid values
- Any numeric value
Question theme (question_theme)
Description
It allows you to use customized themes for the respective question.
Available options
- Your created question themes which are located under the Question themes in the Themes panel.
See: Question themes
Note: This feature is under development at the moment.
Relevance help for printable survey (printable_survey_relevance_help)
Description
If you wish to print a survey, you can also print the relevance equations for each question. But, if you wish to offer instead an explanation rather than the expression on the printed form, fill in this box with the text explanation for the relevance equation.
Valid values
- Any text and/or numbers you wish to be displayed on the printable form.
Entrée

- Any number
- Any SGQA code
- Any question code (variable name)
- Any equation, using ExpressionScript syntax, without surrounding curly braces.
Equals sum value (equals_num_value)
Description
Sets the sum total of all predefined answers that will be accepted. For example: Setting a value of 20 for this attribute would mean that the only acceptable total for all items would be 20. A value of 15 or 60 would be unacceptable.
If the option Value range allows missing is set : the sum value are not checked if whole questions are not answered.
Valid values
- Any number value
- Any SGQA code
- Any question code (variable name)
- Any equation, using ExpressionScript syntax, without surrounding curly braces.
Integer only (num_value_int_only)
Description
If enabled, the respondents will be able to introduce in the box only integer values.
Available options
- Yes
- No (default)
Maximum sum value (max_num_value)
Description
This setting is available in the multiple numeric and numeric array input questions. When this attribute is set, the input value(s) (depending on the type of question) must meet this criteria - the (sum of) number(s) has to be smaller than the value you type in this box. Otherwise, the respondent will not be able to submit her answer.
Valid values
- Any integer value above 0
- Any number
- Any SGQA code
- Any question code (variable name)
- Any equation, using ExpressionScript syntax, without surrounding curly braces.
Example
- Setting a value of 20 would mean that the total value of all numbers entered in all input boxes for this question may not exceed 20. Totals of 21 would not be allowed. A total of 15 would be acceptable.
Minimum sum value (min_num_value)
Description
This setting is available in the multiple numeric and numeric array input questions. When this attribute is set, the input value(s) (depending on the type of question) must meet this criteria - the (sum of) number(s) has to be higher than the value you type in this box. Otherwise, the respondents will not be able to submit her answer(s).
If the option Value range allows missing is set : the minimum sum value are not checked if whole questions are not answered.
Valid values
- Any integer value above 0
- Any number (using . (dot) for decimal separator)
- Any SGQA code
- Any question code (variable name)
- Any equation, using ExpressionScript syntax, without surrounding curly braces.
Example
- Setting a value of 10 would mean that the total value of all numbers entered in all input boxes fr this question may not be smaller than 10. Totals of 9 would not be allowed. A total of 12 would be acceptable.
Maximum characters (maximum_chars)
Description
This allows you to set the maximum number of characters that can be entered for a text based question. Entering a value of, say, 20 will mean that the participant cannot enter any more than 20 characters.
Valid values
- Any integer value above 0
Value range allows missing (value_range_allows_missing)
Description
This attribute applies to the multiple numerical question type. If enabled, a survey respondent can skip answering the multiple numerical question even if equals_num_value or min_num_value are set.
Available options
- On (default)
- Off
Maximum value of the numerical input (max_num_value_n)
Description
Maximum value of the numeric input that can be introduced in the input box by the respondent.
Valid values
- Any integer value above 0
- Any number
- Any SGQA code

This function can be used to ensure that a user selects at least a certain number of answers in a multiple choice question.
Valid values
- Any integer value above 0
- Any number
- Any SGQA code
- Any question code (variable name)
- Any equation, using ExpressionScript syntax, without surrounding curly braces.
Example
If set to X (a random number), the users can submit the survey form if they select at least X checkboxes. If this option is utilised for ranking questions, this ensures that at least three items are ranked before allowing the respondent to submit the answers/survey.
Please note that if you use this attribute with Ranking questions, you have to set the question to non-mandatory. Otherwise, all the items need to be ranked which is counter-intuitive if you decide to use the min_answers function too.
Maximum answers (max_answers)
Description
It can be used to limit the total number of answers a user can select in a multiple choice question.
Valid values
- Any number value
- Any SGQA code
- Any question code (variable name)
- Any equation, using ExpressionScript syntax, without surrounding curly braces.
Example
If set to 2, the user will only be able to check at most two checkboxes or one checkbox + fill the "Other" field (if any). For the Ranking question type, the participant would be able to select maximum two items.
Array filter (array_filter)
Description
The Array filter setting allows you to use any multiple choice question to select or set which responses are displayed in a subsequent list, array or multiple choice question.
- Multiple choice
- Multiple choice with comments
- Multiple short text
- Multiple numeric
- Array (5 point, 10 point, Yes/No/Unknown, Increase/Same/Decrease, Column)
- Array (Dual Scale, Text, Numbers)
- Ranking
Furthermore, each of these question types can be filtered.
The only exception is Array (Column), which can filter other questions, but not itself.How to set a filter
To set a filter, enter the question code of a multiple options question in the array filter box of the question you are currently editing. The respective question will be used as the source of information for the current question, the selected answers from the previous question being retrieved and used as answer options for the current question. For example, if your source multiple option question code is "Q1", enter "Q1" into the 'Array Filter' box to start the filtering process of the answers. Only the answer options that are selected in question Q1 will be visible in the array_filter-ed question.
The subquestion codes used in the first question must coincide with the subquestion codes from the second one. Otherwise, the array filter function will not filter the answers to the first question. Note: When you want to filter the "other" answer option from the first question, you need to provide a subquestion for this answer in the second question and the subquestion code for this answer needs to be "other". Check the below example to better understand how the whole system works.
Cascading
The selected options can be displayed in cascade. This means that you can select a question which filters another question, which filters another question, and so on.
Array filter example
Let's take a look at the following example to better understand the power of this setting:
In the screenshot from above, we got two questions. The first one is a multiple short text question type, while the second one is an array dual scale question type. The answers you provide in the first question will be listed in the second one. Technically, the answers you provide to the subquestions from the first question are filtered and displayed in the second question.
This example can be downloaded from the following link: limesurvey_group_32.lsg. Import this question group into your LimeSurvey installation.
Array exclusion filter (array_filter_exclude)
Description
The Array filter exclusion setting allows you to use any multiple choice question to select or set which responses are NOT displayed in a subsequent list, array or multiple choice question.
- Multiple choice
- Multiple choice with comments
- Multiple short text
- Multiple numeric
- Array (5 point, 10 point, Yes/No/Unknown, Increase/Same/Decrease, By column)
- Array (Dual Scale, Text, Numbers)
- Ranking
Furthermore, each of these types of questions can filtered.
The only exception is Array by column which can filter other questions, but it cannot be filtered.How to set it up
Enter the question code of a multiple options question in the array exclusion filter box of the question you are currently editing. The respective question will be used as the source of information for the current question, the non-selected answers from the previous question being retrieved and used as answer options for the current question. For example, if your source multiple option question code is "Q1", enter "Q1" into the 'Array exclusion filter' box to start the filtering process of the answers. Only the answer options that are NOT selected in question Q1 will be visible in your question.
The subquestion codes used in the first question must coincide with the subquestion codes from the second one. Otherwise, the array exclusion filter function will not filter the answers to the first question. Check the below example to better understand how the whole system works.
Cascading
The selected options can be displayed in cascade. This means that you can select a question which filters another question, which filters another question, and so on.
Example
Let's see together the below example:
In the screenshot from above, we got two questions. The first one is a multiple choice question type, while the second one is a multiple choice with comments question type. The answers you provide in the first question will be excluded from the second one. For example, if you select the ComfortUpdate option (that has the subquestion code 'SQ1') and the Plugin option ('SQ4'), the 'SQ1' and the 'SQ4' subquestion correspondents from the second question will be excluded. In our screenshot, we can observe that only the unselected options in the first question and displayed in the second one.
This example can be downloaded from the following link: Limesurvey_group_array_filter_exclude.zip. Import this question group into your LimeSurvey installation.
Array filter style (array_filter_style)
Description
This function allows you to choose how the array filtered subquestions are displayed. They can either be "hidden" or "disabled".
To learn how to filter subquestions, please read the following wiki section.Available options
- Hidden (default) - if this option is selected, then the previously selected subquestions will not be displayed in the second question.
- Disabled - if this option is selected, then the previously selected subquestions will be greyed out and become unselectable.
Example
If you wish to use the "disabled" option, then the previously selected subquestions will be displayed like this:
Exclusive option (exclusive_option)
Description
The exclusive option attribute takes the code of an answer in a multiple option question so that when clicked on its corresponding checkbox, all the other previously checked options will get unchecked and get marked as read-only (=disabled). This function was created to ensure the data integrity when one of the multiple options in a multiple option question implies that no other option can be selected too. Basically, this feature marks the other attributes as being irrelevant.
Example
For a short explanation on answer codes, check first the following wiki section. Once understood, introduce the "AnswerCode" that will trigger the function once selected.
Below, you may see an example where the exclusive option attribute is used.
You can see in the first screenshot that some non-LimeSurvey options are selected:
If you click on the marked option (which is entered in the exclusive option box), the other options will get unmarked and disabled, being left only with the current option checked:
To take a closer look at our example, import the .lsq file into your LimeSurvey installation:
File:Example exclusive option question.zip.
Randomization group name (random_group)
Description
It places the questions into a specified randomization group, all questions included in the specified group being displayed in a random order to the survey respondents.
You can find a sample survey using randomization group name in ExpressionScript sample survey.
Valid values
Just enter any string you like (for example: 'group1'). All question which have set the same string within the randomization group name box will have their place in the survey randomized (=randomly exchanged among each other).
Preview
To preview the questions use the preview survey instead of the preview question group function, as the second has been reported to not show the questions in a randomized order.
Question validation equation (em_validation_q)
Description
This is an equation that is used to validate the entire question (e.g, all of its parts collectively for a multi-answer question). If the question fails the validation criteria, then em_validation_q_tip message will be displayed (it uses the CSS style .error). This tip uses the .em_q_fn_validation CSS style, which is hidden by default within template.css.
The main difference between this feature and the subquestion validation equations (em_validation_sq option) is that for this feature, if the question (or question parts) fail validation, then an error message could be shown. For the subquestion validation, each text entry cell (e.g., in an array question type, but it can also be applied to single entry question types) will be styled so that the background color is (light) red.
Valid values
- Any equation that makes use of the ExpressionScript syntax, without surrounding curly braces.
Example
- You want to collect demographic information from users via a multiple short text question, and you want to validate that the user has entered a valid email address and phone number.
This example shows how the question looks with invalid answers:
And here is what it looks like with one invalid answer:
Here is how you edit a question to enter that information:
And here is part of the Show Logic File output that lets you check the accuracy of your expression and ensure that there are no syntax errors:
As you can see, the validation equation tests that both the email and phone number are either empty or match a regular expression filter.
The validation tip only shows the warning message if the phone or email appears invalid.
Hint: In order to create complex validation messages, read about the usage of the ExpressionScript.
If you wish to import the example from above into your LimeSurvey installation, download the following .lsq file: Em_validation_q_example.zip.
Hint: Remember, LimeSuvey uses the Perl syntax for regular expressions, so they should start and end with / (slash character)!
Tip for whole question validation equation (em_validation_q_tip)
Description
If you are using the question validation equation, you can use this box in order to display an optional message as question tip on how the question has to be filled out.
Valid values
- Any string or equation that makes use of the ExpressionScript syntax.
Example
See the example from the question validation equation wiki section- it shows how the tip can be tailored to show which parts of a multiple short text question fail the validation criteria.
Sub-question validation equation (em_validation_sq)
Description
This is an equation that is used to validate each subquestion (text field) individually. Any text field that does not pass these validation conditions will have its background color turned pink (using the .em_sq_fn_validation CSS style) to highlight the error. Note that this is available in addition to the regular expression-based validation option.
Valid values
Any equation that makes use of the ExpressionScript syntax, without surrounding curly braces.
Examples
For example, if you want to allow only numbers that are a multiple of 3 as answers, the equation would be:
(this / 3) == floor(this/3)
The reserved variable this is automatically replaced by a reference to the active text entry cell.
Tip for sub-question validation equation (em_validation_sq_tip)
Description
If you are using em_validation_sq, this is an optional message/tip that will be displayed if the introduced answer is incorrect.
Valid values
- Any string
Example
- Continuing the example of validating emails, the tip might be "Please enter valid email addresses."
