I want to customize the databased tree menu on a left navigation bar. I
could able to build area menu for Portal site.which some clue/code already
posted in one of the community site.
My problem is I want to generate databased tree menu . I have done it in
aspx format. How do I place it in sharepoint Site?. Is it necessary to
create webpart to merge my application with sharepoint or using some
frames/layer to place the menu? I wanted this because based on the user
access level I need to display the menu control.

When I used IE webcontrol Menu its giving error as Microsoft accepted this
is a bug.
