To access the "Preferences" menu, click on the down arrow next to your login email address (top right of the page in Sitebuilder). The menu will open, with three options:
- Show Widget borders: you can select or deselect the box that will allow you to choose the way the widgets appear on the Sitebuilder page.
- If you choose to have widgets with borders you will see each widget displayed on the page. If you choose not to show widget borders, the page in the Sitebuilder will be more like the published page. You can try both options and see which one you prefer.
- Show the right sidebar: you can select or deselect the box that will allow you to choose to have the sidebar displayed in the Sitebuilder while you work.
