What is the best way of implementing multi-level lists/bullets in php?

What I’m trying to implement is a system to take in short phrases, and categorize them within sections. However, at the same time, I would like to have each section to be collapsible and capable of having sub-sections within them.

For Example:
Section 10
Section 10.X
Section 10.X.X

I was thinking of having each sub-layer as an array, but I realize that I’ve seen the same type of collapsibility in many places, and they all seem to be similar. Maybe there already is a package or library that does this? And if there is, how should my data-structure for keeping each entry be structured?

    Your bullets are being done in HTML, as PHP merely generates HTML code. Consider using nested <ul> tags.

    The collapsing is most probably going to be javasscript. (Although I wonder if the CSS :active psuedoclass would work in supportive browsers…)

    Regarding the package, I’m not sure. You essentially need a recursive list generating function.
