IE 7 Compatible?

[nealsu]

We have client a client using IE 7 and we are having trouble with the collapsible. Is IE 7 not supported?

Collapsible Version: 2.1
jQuery Version: 1.9.2

It should work on IE 7, someone had an issue using headings in the past but switching to divs fixed the IE issue reported.
