How to use

Add a new block to your form and then select the question type Checkbox (single). 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 checkbox block has the following advanced options:

  • Placeholder

    By default the name of the block will be used as the label for the checkbox. By enabling the Placeholder feature you can show the name of the block on top of the checkbox and show the placeholder as the label for the checkbox.

  • Labels

    By default the checkbox will be marked as Checked or Not checked in your dataset (your results). By enabling the Labels feature you can overwrite these labels in your dataset with your own values (more information about labels).

  • Score

    You can attach scores to the checkbox states to perform instant calculations. By enabling the Score feature you can enter the desired score values (more information about instant scores).
