Journal v.3.2 BETA has been released. Access download page ➝

Catalog Layout

The Catalog layout does not exist in Journal > Layouts > Catalog... it needs to be created  in Opencart > Design > Layouts...

Create a new layout, give it a name like Catalog, and then give it a new route of like so: https://cln.sh/v6Y4xWSN

 

You will then have the layout available in Journal > Layouts > Catalog... where you can activate the Left Column and add your Filter module to it. Just like it's on the Category layout.
