Editable template regions control which areas of a template-based page a user can edit. Before you insert an editable region, save the document you are working in as a template.
If you insert an editable region in a document rather than a template file, an alert warns you that the document will automatically be saved as a template.
You can place an editable region anywhere in your page, but consider the following points if you are making a table editable:
You can mark an entire table or an individual table cell as editable, but you can’t mark multiple table cells as a single editable region. If a <td> tag is selected, the editable region includes the region around the cell; if not, the editable region affects only content inside the cell.
You can easily identify and select template regions in both the template document and template-based documents.
If you’ve marked a region of your template file as editable and you want to lock it (make it noneditable in template-based documents) again, use the Remove Template Markup command.
