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 give 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.

Basic features

Each question block has basic features to present the block the way you need, for example Name, Description and Help text. And most of the question blocks have common options, like the Required and Exportability options.

More information about these basic features can be found in the help article about our form builder.

Additional features

On top of those basic features, the text (single line) block has the following advanced options:

  • Limits

    By enabling the Limits feature, you can control the amount of characters your respondents can enter. You can set the Minimum and Maximum character limits.

    Do you want to show the amount of entered characters in your form while your respondent is typing? Click here to see how to use the calculator block for that.

  • Autocomplete

    By enabling the Autocomplete feature, you can 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

    By enabling the Suggestions feature, you can extend your text input with suggestions that popup while the respondent types in your text input (more information).

  • Transform

    By enabling the Transform feature, you can 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

    By enabling the Prefill feature, you can set a fixed initial value of the text block (more information about prefilling).

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. This way your text input can behave as a combination between a text input and a dropdown box.

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