Overview of Page Composer
Page Composer is the application that you use to edit content in pages on your sites. Page Composer provides you with a visual display of the individual pages on your site. Each page has areas and lists that contain your content. You edit or create new content in these areas and lists.
When you edit pages, you edit them in your workspace, rather than as it appears online. You can also preview how your changes will look when published and also view your online content.
This topic shows you how to:
- Open Page Composer and navigate between sites and pages
- Navigate between your sites and site pages
- Preview content
Other topics show you how to:

You open Page Composer in the following ways:

Then the Page Composer navigation menu opens and your site displays in the main window.
Navigating sites and pages
The sitemap or page tree of your site on the left displays the current site, name of the page, and page language. You can open a page by clicking on it to display the page in the main window. You can also use the language and site switchers to switch from one site to another.
You can manage your site tree by creating new pages, separators and links from this site tree. For more information, see Creating pages and menu labels.

By default, the left panel automatically refreshes when:

Coming from Jahia 7 and wondering where Site Settings is?
In Jahia 8, we have split Site Settings in the two following locations:
- Settings for managing content can be found in the jContent>Additional
- Administration pages for site administrators can be found in Administration>Sites
