(Quick Reference)
checkBox
Purpose
Creates a checkbox form field. All the usual HTML elements apply.
Examples
<g:checkBox name="myCheckbox" value="${true}" />Description
Attributes
name - The name of the checkbox
value (optional) - The value of the checkbox
checked (optional) - Expression if evaluates to true sets to checkbox to checked
The
checkBox tag typically only requires the
name and
value attributes and will infer whether the checkbox should be checked or not from the value. However, if you need to override this behaviour the
checked attribute can be used for fine grained control.
