# Required field

### ![](/files/gwTtOG8wYhIvTwu8ZCK1)

You can use this widget to make a field or a complete form required. This bars you from executing a node exit if a form or field is not filled in properly. The required field widget can also be enabled in the behavioral properties of a Form item itself.

<table><thead><tr><th width="276">Property</th><th>Description</th></tr></thead><tbody><tr><td>Data Field</td><td>A datafield of any datatype. This field is checked for value</td></tr><tr><td>Style context</td><td>The color of the negative validation message Green, blue, orange, or red. </td></tr></tbody></table>
