I've been using Accordion controls in many design situations...
I find them useful for:
- Progressive disclosure of long wizards (reduces number of pages)
- Questionnaires where you want to be able to show answers or exit quickly (see diagram below)
- Checkouts e.g. www.johnlewis.com
I wonder why these patterns are not more popular. I can see the advantages... what are the disadvantages?
A question on UX SE recently mentioned that such controls are falling out of favour... is that true? If so what are the alternative design patterns?
UPDATE Found some interesting information in the question tabs vs accordions. But doesn't address disadvantages of this technique.
