When you create a new menu, GovCMS automatically creates a menu block for the menu. Now we need to assign this menu block to a region on the website.
Go to Structure → Block layout (/admin/structure/block).
Scroll down and find the Footer middle 2 area and click the Place block button.
Search the list for - Related Links. Select Menus block “Related Links”.
Click Place block.
Uncheck the option to "Display title".
Click Save block.
Click Save blocks in the Block layout page.
Check your site to make sure the Related Links menu block is in the Footer.
Next, we’ll restrict visibility so it doesn’t show throughout the site.
