Disclosure Triangles

I am trying to figure out how to use disclosure triangles to show and
hide controls. I am working on a program to generate shop orders for
theatrical lighting (really just saves a little typing, but figure it
would be a good way to teach myself how to program and have something I
could really use). The idea is that a person would only have to open
the disclosure triangles with needed equipment and enter the quantities
for each item. The program would then look through the fields and
generate an rtf file leaving out any line item with a quantity of 0. I
have included a link to a screen shot of what I want it to look like in
the end, though I think I will have to put it all into some sort of
view (NSView, or NSOutlineView as it will need scroll bars if every
triangle is open in the end). I think I can figure out the rest of the
program but all of my searches on disclosure triangles have not lead to
any useful info. I would greatly appreciate it if anyone knows where I
can find more info about this.
