Radio and checkbox groups

Headerly uses the same two selection modes for action items, condition items, and profile groups.

Checkbox

Multiple items can be enabled simultaneously. Use Checkbox when values should be combined, such as several request domains or header modifications.

Radio

Only one item can be enabled. Adding or enabling one item disables the others. Use Radio for mutually exclusive alternatives, such as one active configuration value.

Effect on generated rules

The group type is an editor and storage behavior. The generated DNR rule contains only the enabled values; it does not contain the words radio or checkbox.

Disabled items remain available in the profile but do not affect matching or actions.
