Parent and child checkboxes
|
|
---------------------------
|
|
|
|
Checkboxes can have a parent-child relationship with other checkboxes. When
|
|
the parent checkbox is checked, all child checkboxes are checked. If a parent
|
|
checkbox is unchecked, all child checkboxes are unchecked. If some, but not all,
|
|
child checkboxes are checked, the parent checkbox becomes an indeterminate
|
|
checkbox.
