You know those nifty collapsible fieldsets that Drupal uses? No? Oh... well, let me explain: Drupal often uses fieldsets to represent information, which can collapse at the click of a mouse. This lets visitors to your site hide information or forms they don't care about. It's accomplished using some jQuery wizardry and is uber slick.
What I have created does not use jQuery, and is not uber slick. But, it does provide the same basic functionality. The reason I chose not to use jQuery is so that you are not required to download and install any extra libraries.
Click here to see a demo of it in action. (And use the download link at the top of this post to get the source code).
The idea is you just include the function c_fieldset in your source code, then call it like this:
print c_fieldset("This is my content", "My Title");
And you do not need to worry about any extra jQuery libraries.
So there you go.
