 ====== Use Custom Form Elements ======
-SoSci Survey offers a wide selection of [[:en:create:questions|question types]] -- but sometimes the types provided are insufficient in order to implement a specific display necessary for a question. If this is the case, SoSci Survey is also able to read custom (HTML) form elements. JavaScript or Flash based questions can easily be integrated with these as well.

 There are two major limitations when using custom form elements:
-  - The meaning of the response code will not be saved in the data record. Whereas in a typical selection question, code 1 could be "student" and code 2 could be "employee", you have to keep an eye on this yourself when a custom form element is used.

   - Making a response compulsory can be implemented with a [[:en:create:checks#individuelle_antwort-pruefung|Customized Response Check]]
   - If you want to give the participant the option of using the Back button, or if the page should be shown again if information is incomplete, you have to ensure that your form element shows a response given previously. In order to do so, you can read the value with ''[[:en:create:functions:value|value()]]'' and insert placeholders into the HTML code for the question.

 The solution outlined above assumes that the value from the custom input element (''<input>'' or ''<select>'') will be submitted into the data record.
