It's a pretty simple Widget. The checkbox itself is simply a standard
check box. The event would check all if clicked and unchecked all if
unchecked. The box around it is simply a div styled as a button with a
click event. The click event shows the dropdown which is simply
another collection of divs, each with their own click event to check
the checkboxes of the appropriate type. There's nothing overly unique
about the widget as a whole. Take a look at the Gmail html of the
option and it should be pretty easy to build.
