 **Important:** The question types "selection" and "multiple choice" provide this function by simply checking a box. See [[selection-textinput|Free text inputs within a selection]] how to do this.
-How to achieve a similar output with scales and other question types and how to provide a dropdown selection inside another question is described here. SoSciSurvey provides the PHP-function ''[[functions-output#prepare_input|prepare_input()]]'' to achieve this. We will guide you through using this function using the following example.

 Technically, the input field that is to be added has to be prepared with ''prepare_input()''. In order to place the input field correctly, SoSciSurvey needs a placedholder amongst the original question's items. See further down for details.
+First, the inputs to be used have to be created in the **list of questions**. That means you create a new question, for example a text input question. Second, a placeholder is created, consisting of ''%input:'', the ID of the question or item to be used (e.g., the ID of the text input field that you have just created), and finished by a ''%''. Insert this palceholder whereever the input shall appear.
 **Tip:** Not every question type is available as independent input fields.

 Now we have to add placeholders into the superior question ZE01 (For more options, see [[placeholders|placeholders in questions and items]]. To do so, we add two items with the text "other:" to the superior question's items and add the placeholder:
 The first additional input field derives from item 01 of the question ZE02. The ID of this item is ZE02_01. Use this ID as a placeholder and add percent symbols to it: ''%ZE02_01%''.
 Therefore add an item to the superior question containing the //item text//: "other: %ZE02_01%"

 The other input field is a dropdown selection. We don't just need one item but the whole question "ZE03". So you simply don't mention the item ID inside the placeholder: You use "%ZE03%".
-As the preview still won't show much, you need to use php when assembling the questionnaire. When creating the questionnaire, add the element //PHP-code// ([[php|short guide to php]]).

+====== Optimization =======
+An open-ended [[selection-textinput|text input in a normal selection question]] automatically selects the appropriate option when the respondent writes something into the text field. When text inputs are placed using `prepare_input()`, they are not automatically associated with the corresponding option. This can be set up using [[: de: create: javascript|JavaScript]].
+===== Extended Selection and Text ====
+For example, if a question of the type "Extended Selection" (single or multiple choice) is used, insert the following JavaScript code (e. g. in an HTML code element) under the question.
+<code javascript>
+<script type="text/javascript">
+QuestionSelect.LinkSelect2Text("AU01_12", "TE01_01");
+</script>
+</code>
+The first parameter in the function `QuestionSelect.LinkSelect2Text()` specifies the HTML ID of the radio button or checkbox, in the example the option with the code 12 in question AU01 (an extended selection that allows multiple choice selection). The second parameter is the HTML identifier of the corresponding text input (here the first input in question TE01).
+The function `prepare_input ()` (in the PHP code at the top of the page) would have been used in this example for the identifier ''TE01_01''.
+If more than one open-ended inputs are used, you can simply call the function several times:
+<code javascript>
+<script type="text/javascript">
+QuestionSelect.LinkSelect2Text("AU01_12", "TE01_01");
+QuestionSelect.LinkSelect2Text("AU01_16", "TE01_02");
+QuestionSelect.LinkSelect2Text("AU01_221", "TE01_03");
+</script>
