[development] Re-using collapsible.js for collapsible divs?

[Gerhard Killesreiter]

Hi there,

my proficiency with JS is still near 0, so I need to ask the above 
question. In the past I used to use collapsible fieldsets to hide some 
content, but that is semantically wrong and maybe even invalid html. So 
I would like to have a collapsible div instead if fieldset. Anyy 
pointers on how to achieve this? I would prefer to not install extra JS.


Cheers,
    Gerhard
