There is one new feature in Toivo theme version 1.1.0 and couple small tweaks. I added setting in the Customizer for disabling multi-level dropdown menu for narrow screens. You can find it under Theme Settings >> Nagivation Settings.
This is pretty powerful feature and I’m testing my own fork of Responsive Nav here. For example is usefull to disable dropdown manu on narrow screens if you only have few menu items and sub menu. I’ll post more details in near future.
