treeview question

I'm trying to use the treeview again (its been awhile since I used it last)
and I have it reading a web.sitemap file, the issue is when I click on a
menu option its not expanding to show the sub menus. How can I get it to
expand and contract when I click to expand it?


Its showing like this as default

Home
Menu1
Opt1
Opt2
Menu2
Opt1
Opt3


I changed the ExpandDepth to 0 but I can't expand the menus. How can I get
my menu's to expand and contract when clicked? Also, is there a way to not
have the HOME there? I want it all to show as

Home
Menu1
Menu2
Menu3

and so on. thanks
