Radio

A single-choice radio group, for a small set of mutually exclusive options.

Reach for it when you need:

• Mode selection
• A single-choice field inside a Form

Component name: Radio · Category: Input

In the palette: Single-choice radio group

Events

Attach event actions to these in the Event Manager.

Event	Label	Group	Payload
click	Click	Mouse	The DOM event.
dblclick	Double click	Mouse	The DOM event.
contextmenu	Right click	Mouse	The DOM event.
mouseenter	Mouse enter	Mouse	The DOM event.
mouseleave	Mouse leave	Mouse	The DOM event.
change	Change	Input	The DOM event.
submit	Submit	Input	The DOM event.
focus	Focus	Input	The DOM event.
blur	Blur	Input	The DOM event.

Right-click behaves differently in the Designer

contextmenu fires your configured actions at runtime only — in LiveView and in preview. On the Designer canvas the right-click is captured to open the Event Manager, so testing it there will not run your actions. Test right-click in preview.

Notes

Beyond about five options, a Dropdown reads better and takes less space.
