When is it appropriate to use accordions?

Question

Accordions can provide spectacular effects, but in terms of usability, when are they appropriate? For example, in a menu tree with many options, an accordion can provide a better overview of categories. On the other hand, if I want to see all the available options, I need to click a lot.

When do you use accordions?

Thank!

Answer 6

In our large content management app, accordions have proven to be a very effective organizational tool. What is nice about them is that you can quickly jump to what you are looking for without scrolling to see what is available. However, I do not think they should be used if you do not have a large number of controls.
