How to collapse/expand HTML sections?

[cybersphere]

I'd like to know how to create a collapsible HTML section, like what MS do at [live.com...]

What techniques are used to create this type of functionality? Any tutorial links?

HTML alone won't do it, but a combination of css and javascript will. Essentially you set a block-level element such as <div> to render initially with a css rule of display:none - give it a unique ID to identify it. Then use a javascript link to switch that rule to display:block when the link is clicked.

You can find many examples of this on the web by searching for "accordion menu". Just view the code and you'll see that it's not all that much to adapt it to a non-menu situation.

I'm not sure whether MS is currently using this approach on Live,
because they love to go for IE-only approaches and I can't get that
page to load right now, anyway. But the approach I described will
be good cross-browser,
