How to use the text (single line) block

Learn everything you need to know to use the text (single line) block in your forms.

When to use

Use the text (single line) block to let your respondents enter a text answer that consists of one line. Mostly used for short text answers, like personal data.

You also can extend the text input with suggestions to let the respondent select from a list of suggestions you provide them, while they are typing.

How to use

Add a new block to your form and then select the question type Text (single line). You can now customize this block to your needs with the following features:


  • Text
    Use the Text feature for the name/title of this block.
  • Description
    Enable the Description feature to add a description to this block.
  • Placeholder
    Enable the Placeholder feature to add a text inside the empty input control of this block.
  • Help text
    Enable the Help text feature to add a help text to this block.


  • Limits
    Enable the Limits feature to control the amount of characters your respondents can enter. You can set the Minimum and Maximum character limits.
  • Autocomplete
    Enable the Autocomplete feature to use the autocomplete functionality of the respondent's browser to help the respondent to fill out the form as quickly as possible. You can select which autocomplete value you'd like to insert, like the name or address of the respondent.
  • Suggestions
    Enable the Suggestions feature to extend your text input with suggestions that popup while the respondent types in your text input.
  • Transform
    Enable the Transform feature to determine how the answered text should be transformed. For example you can capitalize certain parts of the answer, or convert all characters to lowercase/uppercase.


  • Prefill
    Enable the Prefill feature to set a fixed initial value of this block.
  • Required
    By default this block is not required to fill out by your respondents. Enable the Required feature to make this block required to fill out.
  • Visibility
    By default this block is visible in your form. Enable the Visibility feature to hide it for your respondents.
  • Score
    You can attach scores to the suggestions to perform instant calculations. Enable the Score feature to enter the desired score values. This feature is only available if you have enabled the suggestions feature.
  • Alias
    By default the name/title of this block will be used in your dataset. Enable the Alias feature to use a different name in your dataset.
  • Exportability
    By default the collected data of this block will be stored to the dataset of each result. Enable the Exportability feature to take control over the storage. You can then include/exclude the data from your dataset. Please note that if you exclude data from the dataset you can never see and/or use the given answers from your respondents to this block, because the data is simply not stored at all.

Suggestions feature

You can extend your text input with suggestions that popup while the respondent types in your text input. The respondent can quickly select an item from your suggestions list. Please note that the respondent still can answer any free text, so also something different than the suggestions you supply.

To activate this, enable the Suggestions feature. Now you can add/import your list of suggestions that you want your respondents to choose from.
