Our theme are using WPBakery Page Builder to Create Footer style so you can create unlimited Footers style.
From Dashboard > Footer Builder > Add New Footer. You can drag any element you want to footer.
When you import our demo content through our Theme Options Importer, the Custom Menu will not be enabled. This is due to a limitation in WordPress, because it does not allow custom menu settings to import. But we have it setup so you can quickly enable the Custom Menu.
