If you have multiple sites in an application, you can filter pages by site so that only the pages for a specific site display in Experience Manager.
By default, all sites display in the navigation tree in Experience Manager. If you are only working on pages in a single site you can filter out all other sites.
To filter pages by site:
In the navigation tree, click the dropdown list in the Site field.
If you have only one site in your application, this field does not appear in Experience Manager.
Click the name of the site that you want to display in Experience Manager.
The Site Pages section of the navigation tree updates and displays only the pages of the site that you have chosen.
