title: RadioWidget
type: text/vnd.tiddlywiki
! Introduction
The radio widget displays an HTML `<input type="radio">` that reflects whether a given tiddler field has a specified value. Selecting the radio button sets to the tiddler field to the value.
! Content and Attributes
The content of the `<$radio>` widget is displayed within an HTML `<label>` element also containing the radio button. This means that clicking on the content will have the same effect as clicking on the button itself.
|!Attribute |!Description |
|tiddler |Title of the tiddler to manipulate (defaults to the [[WidgetVariable: currentTiddler]]) |
|field |The name of the field to which the radio button will be bound |
|value |The value for the tiddler field |
|class |CSS classes to be assigned to the label around the radio button |
! Example
This example uses the radio widget to change the `modifier` field of this tiddler:
```
<$radio field="modifier" value="JoeBloggs"> Joe Bloggs</$radio>
<$radio field="modifier" value="JaneBloggs"> Jane Bloggs</$radio>
```
It renders as:
<$radio field="modifier" value="JoeBloggs"> Joe Bloggs</$radio>
<$radio field="modifier" value="JaneBloggs"> Jane Bloggs</$radio>
