Expandable Headers

This is ideal for such things as lists of links and so forth. The visitor with Internet Explorer 4.x sees only the headers, and need only click on the subject that interests him to expand that particular section. Any type of content can be hidden; here I've used a definition list and a table. A second click on the section header contracts it again. Browsers other than Internet Explorer 4.x show the contents fully expanded, so the script degrades well.
