Bei diesem Fragentyp kann der Umfrageteilnehmen bloß eine Zahl als Antwort manuell eingeben.

Die Frage wird den Umfrageteilnehmern wie folgt dargestellt:

N Num.jpg

Eine Beispieldatei kann hier als ZIP-Datei heruntergeladen werden.




Mit dieser Option wird festgelgt, ob eine bestimmte Frage von Umfrageteilnehmern zum Fortfahren beantwortet werden muss. Müssen nur bestimmte Unterfragen beantwortet werden, verwenden Sie das Attribut minimale Antwort in der Registerkarte Logik (nur bei Matrix- oder Mehrfachauswahlfragen).

Help.pngIf you use any of the preinstalled themes and the mandatory question attribute is enabled, a red asterisk will be shown next to the question. If you wish to hide it, please check these instructions.

Verfügbare Optionen:

Validation (using regular expressions) (preg_validation)


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.

Gültige Werte

  • Jeder gültige reguläre Ausdruck




Ist das Ergebnis einer Relevanz-Gleichung 1 oder wahr, ist die Frage im Umfragekontext relevant. Dies bedeutet, dass Sie den Umfrageteilnehmern angezeigt ist. Eine Relevanz-Gleichung kann für jede Frage einer Umfrage angegeben werden.


Wenn Sie die Relevanz-Gleichung speichern, wird sie ausgewertet und die Syntax hervorgehoben. Fehler werden farblich gekennzeichnet, damit Sie sie schnell erkennen und beheben können.

Hint: Um zu überprüfen, ob alle Relevanz-Gleichungen in Ihrer Umfrage korrekt funktionieren, lesen Sie unsere Funktion Umfrage Logikdatei.

Gültige Werte:

  • Jede Gleichung, die der Ausdrucksmanager - verwendet, ohne die geschweiften Klammern.


Hier finden Sie Beispielen für die Syntax-Hervorhebung (derzeit nur auf Englisch).

Erweiterte Einstellungen



Question theme (question_theme)


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.
Help.png Note: This feature is under development at the moment.

Breite Eingabefeld (text_input_width)


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.


  • If you wish to have the input part displayed below the subquestion/label, select the 100% option from the dropdown list.

Hide tip (hide_tip)


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).

Text input box size (input_box_size)

Hint: This features is available starting in version 3.0.0


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.

Help.png 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

Always hide this question (hidden)


If enabled, the question will always be hidden - it will not be displayed to the survey participants. This function can be used in the following scenarios:

  • If you wish to prefill a question with a URL and you want not to have it displayed on the screen. This overrides any conditions used within the survey because the respective question will not even be embedded on the page.
  • If you wish to store or calculate a value on the fly via the Expression Manager.
Help.png Note: A common question type that is used with this function is the Equation one.

Available options

  • On
  • Off (default)

CSS class (css_class)


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.
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.

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.

Relevance help for printable survey (printable_survey_relevance_help)


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.


QS:Maximum chars/de

QS:Min num value n/de

QS:Num value int only/de

QS:Max num value n/de


Randomisierungsgruppenname (random_group)


Ordne die Frage der angegebenen Randomisierungsgruppe zu. Alle Fragen in der gleichen Gruppe werden in einer zufälligen Reihenfolge erscheinen.

You can find a sample survey using randomization group name in Expression Manager sample survey.

Gültige Werte

Geben Sie irgendeine Zeichenkette ein (zum Beispiel 'gruppe1'). Alle Fragen, die die gleiche Zeichenkette gesetzt haben, werden in der Umfrage jeweils zufällig durcheinander ausgetauscht.

Validierungsgleichung für die ganze Frage (em_validation_q)


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 Expression Manager syntax, without surrounding curly braces.


  • 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 Expression Manager.

If you wish to import the example from above into your LimeSurvey installation, download the following .lsq file:

Hint: Remember, LimeSuvey uses the Perl syntax for regular expressions, so they should start and end with / (slash character)!

QS:Em validation q tip/de

QS:Em validation sq/de

QS:Em validation sq tip/de


Insert page break in printable view (page_break)


This attribute is only active when you actually print a survey from the Printable View. It forces a page break before the question.

Available options

  • On
  • Off (default)


Show in public statistics (public_statistics)


This attribute allows the survey administrator to chose if a particular question results should be displayed to the survey participants after they submitted the survey.

Help.png Note: To have the statistics displayed on the last page, do not forget to enable this functionality from the presentation & navigation settings. Otherwise, no statistics link will be displayed at the end of your survey.

The default setting for each question is 'Off' (=Do not show the question statistics to the respondents). You have to enable this for every single question if you want to show the survey statistics of that (those) particular question(s) to the survey participants after the survey submission.

Available options

  • On
  • Off (default)

Display chart (display_chart)


This attribute allows the survey administrator to choose if a chart that contains the question results should be displayed to the survey participants after they filled out the survey.

Available options

  • On
  • Off (default)

Chart type (chart_type)


This attribute allows the survey administrator to choose which type of chart will be displayed to the respondent once he/she finished filling out the survey.

Help.png Note: Do not forget to change the question and survey settings in order to have the charts displayed at the end on the survey. For more details, check the wiki section on the display chart question attribute.
