Core settings

Mandatory (mandatory)

Description

This option lets you require that all parts of the question be answered. If you have a question with multiple sub-questions, and want to require that some but not all parts be answered, use the min_answers question attribute instead.

Valid values

  • Yes
  • No (default)



Relevance equation

Notice.png
Hint: This features is available starting in version 1.92


Description

If the value of the relevance equation is "1" or "true", the question is "relevant" in the survey context, i.e. it is shown to the survey participant. If not, the question is hidden. All questions let you specify a relevance equation. Relevance is the successor to conditions and supports much more complex conditional logic.

Syntax Highlighting

Whenever you save the relevance equation, it will be evaluated and syntax-highlighted. Any errors will be color coded so that you can quickly detect and fix them.

Valid values

Any equation, using Expression Manager syntax, without surrounding curly braces.

Examples

Here are good examples of syntax highlighting


Advanced settings

Answer width (answer_width)

Description

This value sets the answer column width in percentage. For example if you set this to value 60 then 60 percent of the question width will be used for the answer text (in most question types this is the most left column). The remaining width will be equally divided between the answer options.

Valid values

  • Any integer values from 1-100.



Random answer order (random_order)

Description

This attribute causes LimeSurvey to ignore the existing order of answer options/subquestions, and instead it orders them randomly. It is important to note that this random order will be reordered each time the question is displayed, so if someone returns to a question, the order will probably be different from the first time they saw it. Having the answers display randomly is useful to remove the possibility of bias from answers to questions. Please note that if a question has subquestions the order of subquestions will be randomized, not the order of the answer options.

Available options

  • Randomize on each page load
  • Off (default)



Randomization group name (random_group)

Notice.png
Hint: This features is available starting in version 1.92


Description

Place questions into a specified randomization group, all questions included in the specified group will appear in a random order.

Valid values

Just enter any string you like (for example: 'group1'). All question which have set the same string will have their place in the survey randomized (=randomly exchanged among each other).



Always hide this question (hidden)

Description

If you prefill a question by URL you can use this setting to hide the question and its value from the survey participant at all. This overrides any conditions because the particular question is never even embedded in a page. If you just want to hide a question (for example if you want to store a value calculated on the fly) then use Javascript embedded in the question source code.

Notice.png
Hint: The question are not diplay in HTML, it can be set with an equation question or survey URL, but not in javascript


Available options

  • On
  • Off (default)



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 attribute is set, the layout will use dropdown boxes instead of lines of radio buttons

Available options

  • Yes
  • No (default)



Dropdown separator (dropdown_separators)

Description

If this attribute is set, the layout will use the provided text as a separator after answer text and between dropdown boxes. Format is Separator1¦Separator2.

Example

  • No example



Dropdown prefix/suffix (dropdown_prepostfix)

Description

In dual scale questions, if this attribute is set, the layout will use the provided text as a prefix and suffix before and after the dropdown input elements. Format is prefix¦suffix

Examples

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



Array filter (array_filter)

Description

The Array filter advanced settings allow you to use any multiple choice question to select or set which responses display in a subsequent list, array or multiple choice question.

Starting in 1.92, subsequent questions can be filtered on any array question types, 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 types of questions can filtered.

The only exception is Array (Column), which can filter other questions, but can not itself be filtered.

To set a filter

Enter the question code of a multiple options question to use as the source information into the setting for array filter. For example, if your source multiple option question code is "Q1" enter "Q1" into either the 'Array Filter' input or the 'Array Filter Exclusion' input in the advanced settings of the question you want to filter. Only answer options that are selected in question Q1 will be visible in the array_filter-ed question.

Starting in 1.92, you can enter multiple array_filter options for a single question, separated by semicolons

Array filter question settings require the questions being used to have exactly matching lists of answers. If the questions do not have exactly the same set of answers and codes, then the filters will break.

Starting in 1.92, if Q2 has sub-questions that are not present in Q1, they will always be displayed rather than breaking the filters.

Cascading

The Array filter will cascade – that is you can select a question which filters another question, which filters another question, and so on.

Array filter example

Ticking items ‘One’, ‘Three’ and ‘Four’ in the first question results in the entries 'One', 'Three' and 'Four' displaying in the subsequent question which uses array filter

Multi option question

Code:Q1

Question: Which animals do you like?

1 Cat

2 Dog

3 Zebra

Array 5 Point Choice Question

Code:Q2

Question: Rate these animals on a scale of 1 to 5, where 1 is I like them a little and 5 is I like them a lot

Array exclusion filter (array_filter_exclude)

Description

The Array filter exclusion advanced setting allows you to use a multiple choice question to select or set which responses won't display in a subsequent list, array or multiple choice question.

Starting in 1.92, subsequent questions can be filtered on any array question types, 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 types of questions can filtered.

The only exception is Array (Column), which can filter other questions, but can not itself be filtered.

To set a filter

Enter the question code of a multiple options question to use as the source information. For example, if your source multiple option question code is "Q1" enter "Q1" into 'Array filter exclusion' input in the advanced settings of the question you want to filter.

Starting in 1.92, you can enter multiple array_filter_exclude options for a single question, separated by semicolons

The source question has to contain exactly the same list of answers/subquestion as the question you wish to filter. Your question will then only display those answers/subquestion that were not selected in the multiple options question.

If the questions do not have exactly the same set of answers/subquestions and codes, then the filters will break.

Starting in 1.92, if Q2 has sub-questions that are not present in Q1, they will always be displayed rather than breaking the filters.

Cascading

The Array filter exclusions settings will cascade – that is you can select a question which filters another question, which filters another question, and so on.

Example

Ticking items 'One' and 'Three' in the first question results in those questions not being displayed in the subsequent question which uses array filter exclusion

Multi Option Question

Code:Q1

Question: Which animals do you like?

1 Cat

2 Dog

3 Zebra

Array 5 Point Choice Question



Insert page break in printable view (page_break)

Description

This attribute is only active when you actually print a survey from the Printable View. It forces a page break before the question. (Only the Opera browser does not need this since it handles the page breaks accordingly.)

Available options

  • Yes
  • No (default)



Show in public statistics (public_statistics)

Description

This attribute allows the admin to chose if the results of a particular question should be shown to the survey participant after he/she has the submitted he survey. Please note that in general to show statistics to the participant the survey setting 'Public statistics' has to be enabled!

The default setting for each question is 'No' (=Do not show statistics of this question to the user). You have to enable this for every single question if you want to show the survey statistics of that particular question to the participant after the survey submission.

Available options

  • Yes
  • No (default)



SPSS export scale type (scale_export)

Description

Used for SPSS export only. This attribute overrides the default scale guessed by SPSS. To learn what the different measurement scales do, please read the related SPSS documentation.

Available options

  • Default (default)
  • Nominal
  • Ordinal
  • Scale



Minimum answers (min_answers)

Description

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
Notice.png
Hint: This feature changed with version 1.92


  • Any number
  • Any SGQA code
  • Any question code (variable name)
  • Any equation, using Expression Manager syntax, without surrounding curly braces.

Example

If set to 3, the user will only be able to submit the survey form if they have selected at least three check-boxes. In ranking questions, this ensures that at least three items are ranked. Please note that if you use this attribute with Ranking questions please set the question to non-mandatory - because when you leave it at mandatory all items need to be ranked which is counter-active to this feature.


With Array dual scale an completed answer is an answer at each scale.


Maximum answers (max_answers)

Description

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 (New in 1.92 )
  • Any question code (variable name) (New in 1.92 )
  • Any equation, using Expression Manager syntax, without surrounding curly braces. (New in 1.92 )

Example

If set to 2, the user will only be able to check at most 2 checkboxes or 1 checkbox + fill the Other field (if any). At ranking questions the participant would be able to only select 2 items at most.


With Array dual scale an completed answer is an answer at each scale.
