I have a vertical <ul> that is used for sub-navigation.
Each different .htm page has an "active" class attributed to respective <li>.
How can I, semantically, add a caption underneath an active <li>?

I'd like to have the <li> have the caption underneath the bold <li> text; like so:


List Option
caption describing option
underneath bolded text

use a definition list instead

and I get a couple of links in

At first, I planned on using a definition list. But here's the thing...
I only want the "definition", or list description, to be displayed on one particular list element per page.
Is it kosher to have a <dl> with a list of <dt> terms without their respective <dd> definitions, with the exception of one?

So it will be:

<dl>
<dt>option 1</dt>
<dt>option 2</dt>
<dt>option 3</dt>
<dd>here is a little something about option</dd>
<dt>option 4</dt>
</dl>

Is it uncodely to have a <dt> tag listed without an accompanying <dd> description?

By the way, thanks for the link on how to properly code html lists. For some reason I thought you didn't close the <dt> tag until after the open/close of the <dd>.

Sure, there doesn't have to be a description following every term.

I ran it through validator.w3.org direct input within a strict html doctype and it validated. So if W3C approves of it, it must be a-okay.
