Are you trying to make a template?
If so, you will need to code through CSS a sidebar. Float if left, give it some width, and then create your other div and float it left as well.
You can do it through your Resources -> Resources -> Templates section if you want, or simply hard code one and upload it.
You will need to create a Template variable as well, call it [*sidebar*] or something, that way when you go to create a new page (document), you edit your [*content*] section and your [*sidebar*] section as well. They will both have their own text areas to edit, assuming when you set up the TV (template variable), you give the sidebar a Rich Text attribute.
you kinda lost me, but I will give it a shot
will that create the dhtml menus when hovering also?
sorry, I probably sound ignorant
