Reply To: BUG: Open Categories Menu should push Sidebar down instead of blocking it

The example you send has this menu added to the sidebar and it will not work on pages without sidebar like this

or with page heading block like this https://gyazo.com/956dd86332de6bf8a5cbba006aade4e0

Here is a solution we can propose you:

1. Disable option to always show this categories dropdown on the shop and single product page.

2. Add Vertical mega menu widget to your shop and product pages sidebar in Appearance -> Widgets and then it will be always opened.

And you will be able to keep your header menu opened on the home page only.

Kind Regards
