Adding divider lines to h:selectOneMenu dropdowns

[evan k. stone]

I'd like to be able to create an h:selectOneMenu dropdown that has dividers between some of the items to "categorize" them:

Item 1
Item 2
-------------------
Item 3
Item 4
-------------------
Item 5
Item 6
Item 7

...is there away to do that without using a line of dashes (like with CSS)?

Or would I have to resort to using a CSS and DIV-based pseudo-dropdown?

Thanks!
