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

[Rick Faircloth]

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
