Hello,

It is not possible to add the category description into the Shop title area.

You can disable the shop title: Theme Settings > Product Archives > Page title.

Then you need to set off-canvas sidebar in the Theme Settings > Product Archive > Sidebars

Then create the template you want in HTML block and add it to the category description making the rows of HTML block full-width: https://xtemos.com/docs/woodmart/html-blocks-2/#cat_att_tag

If you have any questions please feel free to contact us.

Best Regards
