<div id="1">
<asp:DropDownList  ID="DD1" runat="server">

<div id="option2show">
OPTION 2 Content.
My question is, I want the div with the id of "option2show" to be hidden unless the user has selected option 2 in the dropdown box.

If the user has selected option 1 then nothing will happen, however iff option 2 has been selected then the option2 div will appeaar. I would like this to happen before any submit buttons are press, so i guess onblur of the dropdown box.

Any ideas?

Many thanks
