When starting a new story, you can use a template that provides predefined layouts and placeholders for objects to help you build a story.

Apply a Template to an Existing Story
You can also apply a template to an existing story by selecting the Layouts button in the ribbon.
Once a template is applied, it is shown in the Manually Added section of the Layouts panel, with Additional Layouts available below.

Create a Template
There are prebuilt templates to choose from, or you can also create your own by saving a story as a template.
Saving the story as a template first removes all custom formatting and data, then converts charts, tables, maps, input controls, and value driver trees into empty placeholders.
