Hi,
Adding widgets to different footer sections didn’t work for me.
Supposing you already have SiteOrigin Layout Builder widgets, here’s the solution:
1. Go to any footer section you want (i.e Footer 1, anyone section shall work)
2. Search for the “Layout Builder” widget and add it to the footer.
3. Click-open the dropdown menu just appeared and click “Open Builder”
From that point on it’s just like creating a page with the builder.
Add a row. Select the preferred layout. Add widgets in layout sections.
Hope this helps.
Cheers.
