There are a variety of pre-configured available layouts with a variety of regions (hero, header, sidebar, etc.) on your Open Berkeley pages to help feature and organize your content. To see your layout options and to change layouts, select "Change layout" at the bottom of the page.
Select your desired layout, then hit Save.
After you choose the layout, you will see a "preview" of how your previous regions will be placed into the new layout. You can do a preliminary drag and drop of the existing widgets at this point to get started on the process (you will also be able to drag and drop widgets again after this step). Click "Save" when you're ready.
When you change the layout of a page, you have the opportunity to create a new revision. See Revisions and Configure Widgets for more information. To make the revision log clearer, add a log message every time you create a revision when changing page layout.
Once you hit "Save", you can hit "Customize this page" at the bottom of the page in order to move your widgets around to other available regions as much as you'd like, as well as create new widgets and edit existing ones. See the next page (Configure Widgets) for details.
