Solution 1

In ASP.NET, the adequate control with "plus beside of each group" is System.Web.UI.WebControls.TreeView, http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.treeview.aspx[^].

Solution 2

This link Adding groups to the ASP.NET DropDownList control[^] does not have an expand / collapse structure but it should help you get started.

This[^] should give you an extensible option as well.

ASP.NET DropDownList with OptionGroup support[^] is another neat article.

JQuery can give you one more approach as described here[^].
