Das Feld kann als Pop-Up-Zeitwähler angezeigt werden. In diesem Fall wird die Frage den Umfrageteilnehmern wie folgt angezeigt:



Allgemeine Optionen



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:

  • An
  • Aus (Standardwert)



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

Anzeige als Klappboxen (Dropdownfelder)


Dieses Frageattribut ändert die Darstellung von Datumsfragen zu Dropdownfragen für Tag, Monat und Jahr und Zeit.

Verfügbare Optionen

  • Ja
  • Nein (Standard)


If it is turned on, the question will be displayed in the following way:

D Date DD.jpg

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).

Month display style (month_display_style)


The months can be displayed to the respondents in three ways: by using their short names (Jan, Feb, etc.), full names (January, February, etc.) or the number/position of the month in the yearly calendar (01 for January, 02 for February, and so on).

Available options

  • Short names
  • Full names
  • Numbers

Umgekehrte Antwortreihenfolge (reverse)


If activated, the order of the answers will be reversed.

Verfügbare Optionen

  • An
  • Aus (Standard)


Let's assume that you want to use an Array (Numbers) question type. If this option is disabled (default value), then the possible answers a survey participant can select are: "1, 2, 3, ... , 10". If enabled, the setting will reverse the order of the available answers: "10, 9, 8, ... , 1".

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.

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.




This question option can be used to specify a custom date format. If it is empty, the survey date format will be used.

Gültige Werte

  • The d/dd,m/mm,yy/yyyy,H/HH,M/MM formats can be used to display the date and/or time, while "-", ".", "/", ":" can be used as separators.


  • yyyy-mm-dd - year-month-day;
  • HH:MM - day.month.year Hour:Minute;
  • HH:MM - Hour:Minute (only the time can be selected);
  • yyyy/mm - year/month.

Minute step interval (minute_step_interval)


Hint: This feature changed with version 3.14.12

It's used only input format makes use of minutes ("MM") .

Valid values

  • Any numerical value smaller than 60. Adding a value bigger than 60 is redundant -> only "0" or "00" will be displayed in the dropdown box as possible answers.


In the below example, the minute step interval option was set up to 7:

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)!

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.

Available options

  • Bar chart
  • Pie chart
  • Radar
  • Line
  • PolarArea
  • Doughnut

Datumsangaben und ExpressionScript: Erweiterte Validierung und Berechnung

Limesurvey macht es relativ einfach, Daten mit den Feldern date_min und date_max zu validieren (siehe oben). Benutzen Sie diese wann immer möglich. Wenn Sie mehr Lust haben, können Sie mit dem ExpressionScript und der Funktion strtotime () mit Datumsangaben arbeiten (und rechnen). Es berechnet die Anzahl der Sekunden vom 1. Januar 1970 bis zu einem bestimmten Datum. Beispiel: Wenn Sie in einem Fragetext die Anzahl der Tage anzeigen möchten, die seit einem Abreisedatum (in einer vorherigen Frage abgefragt) und heute vergangen sind, können Sie den Ausdruck {(strtotime("now")-strtotime(departure))/60/60/24} verwenden. Bitte beachten Sie, dass strtotime() mit vielen verschiedenen, aber nicht ALLEN Datumsformaten arbeitet. Das Standarddatumsformat von Limesurvey (MM-DDD-YYYYY) funktioniert NICHT mit strtotime(). Um Probleme zu vermeiden, stellen Sie bitte Ihre Umfrage auf eines der folgenden Datumsformate ein: YYYY-MM-DD, YYYY/MM/DD, DD.MM.YYYY, MM/DD/YYYY, DD-MM-YYYY.

Example: if you want to display in a question text the number of days that have passed since a departure date (asked in a previous question) and today, you can can use the expression {(strtotime("now")-strtotime(departure))/60/60/24}.

Please be aware that strtotime() works with a lot of different formats, but with not all of them! For example, Limesurvey's default date format (MM-DD-YYYY) does NOT work with strtotime(). Please set your survey to use one of the following date formats to avoid problems: YYYY-MM-DD, YYYY/MM/DD, DD.MM.YYYY, MM/DD/YYYY or DD-MM-YYYY.

  Dates in Limesurvey are saved as a string (text format). The ExpressionScript converts all dates part of an expression into the standard format "yyyy-mm-dd HH:MM:SS". This makes it much easier to compare dates in an expression (e.g. "date1>date2"). If you need a datestring in the format it was asked in the question, use the ".shown" attribute (e.g.: You were born on the {birthdate.shown}.)
