Now we can create a Dynamic Web Template (DWT) page that will contain our menu and that will be used by other pages.

Choose File > New from the main menu and click Blank page. This will add a new page to our project.

To save the new page as DWT page choose File > Save. This will bring up the Save As window. As Save as type at the bottom choose Dynamic Web Template (.dwt) and specify the file name, e.g. template. The new page will be saved as template.dwt.

Now we need to create an editable region so pages that will use the template can define their own contents. On the template page press Enter to move the cursor down, right-click to open the pop-up menu and choose Manage Editable Regions.... As a region name type e.g. body and click Close.

The new region will appear on the template. The space above the region is the place where we will later put our menu.
