How to Open a Dreamweaver Template from any Page Created from a Template
If you're not sure which Dreamweaver template was used to create a page, you can open the template while you have the page open, make changes to the template, and update all the pages created with it by following these steps:
Open a document that uses the template that you want to change.
Choose Modify→Templates→Open Attached Template.
The template opens.
Use Dreamweaver's regular editing functions to modify the template as you would edit any page or template.
If you've altered the template, the Update Template Files dialog box appears.
Click the Update button to modify all the pages listed in the Update Template Files dialog box.
(Click the Don’t Update button to leave these pages unchanged.) If you choose Update, Dreamweaver automatically changes all the pages listed in the Update Template Files dialog box.
If you edit a template and have an open page that was created from that template, the changes are automatically applied to the open page but you need to save the page before closing it to save the changes.
You can also apply changes to all the pages created from a template by using the Update Pages option. To do so, open the template, and then make and save your changes without applying those changes to pages created with the template. Anytime later, choose Modify→Templates→Update Pages to apply the update.
