Expandable Outlines | 3
creating expandable/collapsable outlines in both browsers
This tutorial can be appreciated by users of any browser, any version. The in-line examples will work only in Netscape Navigator 4 or Internet Explorer 4, Release.
This technique was developed after a suggestion by Anders Lund.
Those of you who visit our links page regularly will be pleased to know that we've minimized the scrolling needed to browse the link list, by presenting the page in an expandable/collapsable outline format for DHTML browers.
In fact, the whole list is reproduced here. Click on the triangle images to expand and collapse the individual headings or even the complete list:

Admittedly, this technique is becoming popular with IE4-specific pages. We, too, will discuss the Explorer methods in detail, but we'll move a step further to create a Navigator version, and finally a cross-browser version of expandable outlines.
In This Column
We will discuss:
- the CSS1 display property
- browser support of display (surprising results)
- simple outlines in Explorer
- outlines with swapped images in Explorer
- outlines in Navigator
- cross-browser outlines
- multi-item expansion/collapse with one click
Along the way, we'll explore for the first time:
- how to use the powerful new Explorer methods, tags() and item()
- how to use the Navigator scrollTo() method.
We start with an overview of the display property.
