Render A Checkbox Input Field

Renders an HTML <input> element of type checkbox, whose "checked" status is initialized based on whether the specified value matches one of the elements of the underlying property's array of current values. This element is useful when you have large numbers of checkboxes, and prefer to combine the values into a single array-valued property instead of multiple boolean properties. This tag is only valid when nested inside a form tag body.

WARNING: In order to correctly recognize cases where none of the associated checkboxes are selected, the ActionForm bean associated with this form must include a statement setting the corresponding array to zero length in the reset() method.

The value to be returned to the server, if this checkbox is selected, must be defined by one of the following methods:

Also note that a map backed attribute cannot be used to hold a the String[] for a group of multibox tags.
