The FAQ accordion

Each question is a real button inside a heading. Click, Enter or Space open and close it; the arrow keys, Home and End move between questions. Closed answers are found by the browser’s search (Ctrl+F) and open by themselves.

• Topics: with All topics and Group by topic on, each topic is a heading with its questions; questions without a topic come last, under Other questions. Choose a topic in the block to show only its questions.
• Order: the Order number of each question, then the oldest first.
• Question heading: H3 by default, for a FAQ under an H2 title of the page. Topics take the level above.
• First answer open and One answer open at a time: in Settings for the whole site, or per block.
• How many: 0 shows all, a number shows the first ones.

The accordion takes fonts and colours from your theme. The JavaScript is less than 2 KB and loads only on pages with a FAQ.
