The art of CSS and thus the art of Web design, is the ability to style elements based on their context. You must consider where an element is in the document, which elements surround it, its attributes, content, and dynamic state and even the platform displaying the element (screen, handheld device, TV, and so on).

I'd like to make a hierarchical select box: However, requirements are
only children (that have no children themselves) are selectable.
So here's a snip of what the select box's options might look like:
US Department of Education
-Office of Safe and Drug Free Schools
US Department of Health and Human Services
-Substance Abuse and Mental Health Services Administration
--Center for Substance Abuse Prevention
--Center for Substance Abuse Treatment
--Center for Mental Health Services
--Office of Policy and Coordination, Planning and Budget
-Centers for Disease Control and Prevention
-Administration for Children and Families
--Family and Youth Services Bureau
-National Institutes of Health
--National Institute on Drug Abuse
---Office of the Assistant Secretary for Planning and Evaluation
I took a look at 's 'disable' attribute, which would be
perfect. Unfortunately, it seems almost wholly unsupported.
Other options are:
* controlling what is selectable using JavaScript. The problem is
that while I can use JS, I _cannot rely on it_ so I would have to
back this up with server-side validation. Problem is it might be
awkward to explain to a non-JS user what's selectable and what's not.
* Break the interface into (potentially) three different pages (one
for each level), and have a select box on each page.
* Make the whole thing a radio button list, and just display the
giant hierarchy in the form (uggh)
Elegant solutions, anybody?
Thanks,
Jamie
