[jQuery] How to make an element *not* have a function attached...


Strange question, perhaps...but...
If I have an element that has an function from a plug-in
attached to it, such as:
$(function() {
    $('#myTextarea').expandable();
});
How would I then be able to make #myTextarea "not .expandable"...
$('#myTextarea').expandable('disable'); ...
Is this something that can be controlled from the page code, or
does something have to be built into the plug-in to allow this?
Thanks,
Rick
