Currently the "collapse" documentation jumps straight into the accordion example and then mentions in passing the slightly simpler example of using a single component to expand/collapse a region after that.
This leaves some room for misunderstanding; for example I spent a while not realising that I'd set data-target in my links, which makes the page jump around when clicked as the default action isn't prevented (see [1]).
This proposes a simple example first up, using a link and a button to expand a div. It also explicitly mentions use of href and data-target. The more involved accordion example then follows unmodified.
