# Checkbox

The Checkbox field is a standard input field which allows you to define the checked and unchecked values. You can also choose the text beside the checkbox. \
\
There is also a unique feature in this field where you can dynamically change what the checked value would be. This feature is designed to change the purpose of the checkbox from a Yes/No to various values that may change based on the user activity.

![A standard checkbox where the checked and unchecked values are defined when building the field itself.](https://1186088597-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-MSr2uF2m-DtSpCxknCK-887967055%2Fuploads%2F6Zd9ZlXlS9pOTGzTSzQY%2Fimage.png?alt=media\&token=8cc9efa8-8bab-4f2e-8631-cd972d52da77)

![In this example, we are dynamically setting the value of the checked boxes to "Adrian". Below will show the data once submitted.](https://1186088597-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-MSr2uF2m-DtSpCxknCK-887967055%2Fuploads%2FN1peYnlgyjAYj0xZxp53%2Fimage.png?alt=media\&token=8f4c26e2-11f6-4999-b448-25f3daecc356)

![As per above, "Adrian" is considered the checked value, as opposed to looking for the values defined when building the field.](https://1186088597-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-MSr2uF2m-DtSpCxknCK-887967055%2Fuploads%2F9r5XzuyvDhYBXyhJqlJM%2Fimage.png?alt=media\&token=61c3ab71-7b4e-4a9e-97c1-164981962496)
