! Introduction
|
|
|
|
The checkbox widget displays an HTML `<input type="checkbox">` element that is dynamically bound to either:
|
|
|
|
* the presence or absence of a specified tag on a specified tiddler
|
|
* the value of a specified field of a specified tiddler
|
|
|
|
! Content and Attributes
|
|
|
|
The content of the `<$checkbox>` widget is displayed within an HTML `<label>` element immediately after the checkbox itself. This means that clicking on the content will toggle the checkbox.
