The steps to create the cross-frame menu are as follows:

1. Create a frameset page, in which there are three frames. In this sample, we create a frameset page named "index.htm", which has three frames: left, top and main. The page "left.htm" is loaded in left frame window, the page "top.htm" is loaded in top frame and the page "main.htm" is loaded in main frame window.
   
   
2. Run DHTML Menu program standalone. Create a menu to be inserted into the left and top frame as you like.
   
   
3. Add link.
   As all the pages are in the same directory in this sample, to let a page loaded into the main frame, just input the file name such as "step1.htm" to the Link field and enter the frame name "main" (case sensitive) in the box to show popup menu.
   
   (If these pages are NOT in the same directory, you'd better use root relative path in the Link field, like /foldername/step.htm, or absolute path like https://www.yourdomain.com/foldername/step.htm. Enter the frame name "main" in the box to show popup menu as well.)
   
   
4. After you finish configuration, save the menu to a folder. Then the .pgt file of the menu as well as js files and image files will be auto saved there. In this sample, all the menu files are saved to the same directory as the frameset page.
