Easy to install, and does the job nicely.

My only gripe is concerning the short intro text. I hoped to be able to show the first n words of an article in the collapsible div, but there was no support for that. Either the full article, a short description, or no description (no short description available).

But it turned out to be easy enough to code this, so it now works as I want it to.

Now I just want to use SectionEx to display Weblink categories under the article categories. This might not be so easy...
