Well, semantically you have a nested un-ordered list. So in your case it would result in something like:
<ul> <li>Item <ul> <li>Item <ul> <li>Item <ul> <li>Item <ul> <li>Item</li> <li>Item</li> </ul> </li> <li>Item <ul> <li>Item</li> <li>Item</li> </ul> </li> </ul> </li> <li>Item <ul> <li>Item <ul> <li>Item</li> <li>Item </li> </ul> </li> <li>Item <ul> <li>Item</li> <li>Item</li> </ul> </li> </ul> </li> </ul> </li> <li>Item <ul> <li>Item <ul> <li>Item <ul> <li>Item</li> <li>Item</li> </ul> </li> <li>Item <ul> <li>Item</li> <li>Item</li> </ul> </li> </ul> </li> <li>Item<br /> <ul> <li>Item <ul> <li>Item</li> <li>Item</li> </ul> </li> <li>Item <ul> <li>Item</li> <li>Item</li> </ul> </li> </ul> </li> </ul> </li> </ul> </li> </ul> Styling that sounds like a good challenge. - A -----Original Message----- From: listdad@webstandardsgroup.org [mailto:[EMAIL PROTECTED] On Behalf Of Christian Montoya Sent: Monday, 13 November 2006 10:38 a.m. To: wsg@webstandardsgroup.org Subject: [WSG] semantics for a binary tree? A friend of mine needs to represent a pedigree (specifically for horses) and is looking for a semantic solution. The current representation: http://www.imperialegyptianstud.com/the-stallions/imperial_shehaab.html uses a table with various "rowspans" on the cells. I figured this was a sort of binary tree but I can't find anything about representing such a thing semantically in HTML (kind of funny considering HTML is a tree structure, yeah?) What would you recommend in this case? He could do something complicated with lists but then it would be very hard to style (especially horizontally). My initial reaction was just, keep using the table. Thoughts?
