The Site Switcher is shown in the top left corner of the Refined Site and is used to navigate between the Refined Sites of this instance. Hiding it will give the appearance of an independent site, whereas showing it will give users more navigation options.
You can decide whether a site displays the Site Switcher and if that site should be listed in the Site Switcher on other sites.
Go to the Refined Administration.
Go to the Site Builder tab.
Click on a site’s Cogwheel > Edit site.
