I created a layered navigation using an attribute to filter colors. This color filter is the only filter I am using and works in desktop view well. But in mobile view the filter doesn't show up. I also tried it in Luma Theme but it doesn't show up there too. Do I need to activate layered navigation for mobile somewhere?
Magento Blank theme (and I assume Luma as well) shows the layered navigation in the mobile layout. I believe the exception is if you're using the
2column-right layout. Anything in the right column is hidden for mobile layouts.
