Example: If you want to store a standard WBS element as a template, select Standard templates or Standard WBS elements.
A dialog box appears.

Create by Copying.These templates are kept here until you remove them. To do so, choose Remove from templates or Empty templates in the context menu.

If you have not stored project data in the templates, you can access other templates by choosing Create with other template in the context menu.
