how to arrange vertical sub menu controls in inside the vertical main menu control

If you are using the asp.net menu control then you have to bind it to a data source, either an xml file or hardcoded inside the menu control. In any of this cases the outcome has to be hierarchical with parent and child nodes. If this data source is structured correctly then the menu control will take care of the arrangement of the menu items and submenu items. Of course you have to make sure that the menu control properties will be set correctly especially orientation (horizontal or vertical), Display Style (Static or Dynamic) and their levels accordingly.
