Any page added to the website, whether they be static pre-existing pages or dynamic pages
created by DTIAdminPanel, can be added to the menu.
Accessing the Page List from within DTIAdminPanel will
allow a menu structure to be created.
Once a DTIMenu object is placed on the page any subset of the menu structure
can be displayed back to the user.
By setting the SelectedCss property the menu control will keep track of what page it is
currently on and apply the class name in SelectedCss to the anchor tag for that page.
