OK i read through this and tried some settings but not everything works as expected.

As i understand i should be able to show a hidden sidebar via a Button on the Shop and Category pages. Something like this from your demo: https://woodmart.xtemos.com/shop/?opt=hidden_sidebar

I’ve made some «Filter Blocks» with the HTML blocks and Elementor but the «off canvas column button» does not trigger the sidebar. The only place where this works so far ist the category pages which seems to use a standard Layout. (here for example: https://schweizer-trauerkarten.ch/produkt-kategorie/trauerdanksagungen/)

The Sidebar that opens should then show two Atributes (color and Size) as s Swatches .

When i open the area «Design» -> «Widgets» in the Backend i’m presented by a bunch of errors, why?
The content of the filter Sidebar has to be defined there right?

Could you please assist with this?

kind regards
Chris
