[HTML] Drop Down List - Selected?

[Iszak]

You don't need to put selected="selected", as selected is a bool value.

You use XHTML, you should know that just having

selected

is invalid for all XHTML doctypes, and only valid in HTML 4.01, but

selected="selected"

is valid in both - so hence my statement is correct.

I have to agree with iszak, I've found selected="selected" to have lesser issues when designing for multiple browsers and doc types.
