DHTML Menu Builder allows you to easily insert a menu into an existing frame-based web site no matter what kind of frameset configuration you use. After populating the menu with items and setting graphical options, you should open the Template window (you will find it in the Window menu) and click 'Import template (source) file'. After selecting the main frameset definition page the template window should display your frameset configuration in a visual way so you can simply use the mouse to select the top-level, pop-up and default target frames. After setting all the frame names as well as the insertion point (the spot where the menu bar is physically inserted into HTML page), all you need to do is generate the menu by selecting Menu / Generate Menu / Save To Disk and selecting proper HTML file (it should be the frame into which the menu bar is to be inserted).
