Answer width (answer_width)

Description

This value sets the answer column width by using a percentage system. For example, if you type in this field 40, then 40 percent of the width of the question will be used for answers. The remaining width will be equally divided between the subquestions.

Valid values

  • Any integer value from 1 to 100.


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).


QS:Orden aleatorio


Repeat headers (repeat_headers)

Description

This option can be used if you add to a question a high number of subquestions. If this is the case, use this option in order to tell LimeSurvey after how many subquestions should the headers be repeated.

Valid values

  • Any integer values;
  • The default value is 0 - the repeat headers function is deactivated.


QS:Pregunta tema

CSS class (css_class)

Description

If you want to add special CSS classes to certain questions, you can enter the CSS class name(s) in this box. Make sure you leave an empty space between different class names.

Valid values

  • Any text string with a space between different CSS class names.
Notice.png
 Hint: You can also insert an expression in this box (New in 3.0.0 ). Remember that the output of the expression will not be updated dynamically.


Important.png  According to the W3C, CSS class names can contain only the characters [a-zA-Z, and 0-9] and ISO 10646 characters U+00A1 and higher, plus the hyphen (-) and the underscore (_). They cannot start with a digit, or a hyphen followed by a digit. LimeSurvey encodes CSS classes, but it does not fix it totally.




Header for first scale (dualscale_headerA)

Description

This is the text to be displayed above the first scale of answer options.

Valid values

  • Any text string



Header for second scale (dualscale_headerB)

Description

This is the text to be displayed above the second scale of answer options.

Valid values

  • Any text string



Use dropdown boxes (use_dropdown)

Description

If this function is enabled, the answer options layout will use dropdown boxes instead of radio buttons.

Available options

  • On - dropdown boxes are used.
  • Off (default) - radio buttons are used.



Dropdown prefix/suffix (dropdown_prepostfix)

Description

In the dual scale questions with the dropdown option enabled, if this attribute is set, the layout will use the provided text as a prefix and/or suffix before and after the dropdown input elements. The format is prefix|suffix.

Valid values

  • Any text string.

Examples

  • Suffix with the letters EUR: "|EUR"
  • Prefix with the letters USD: "USD|"
  • Both prefix and suffix: "USD|EUR"

Screenshot prefix:

Dropdown separator (dropdown_separators)

Description

In the dual scale questions with the dropdown option enabled, if this attribute is set, the layout will use the provided text as a separator between the dropdown boxes that correspond to each scale.

Valid values

  • Any text string.

Example

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.


Lógica

Minimum answers (min_answers)

Description

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.

Help.png 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 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".

Help.png 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:

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.

The subsequent questions can be filtered on any array question type, including:
  • 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.

If you wish more questions to be filtered via this option, type the question codes in the box separated by semicolons (;).
Important.png  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:


Example array filter exclude.png


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 (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.

The subsequent questions can be filtered on any array question type, including:
  • 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.

If you wish more questions to be filtered via this option, type the question codes in the box separated by semicolons (;).
Important.png  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.


If multiple choice allow other setting: you can choose other for subquestion code and filter with other checked or not.

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:


Array filter with multipe short text.jpg


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.
