Hello,
You need to enter each category and insert the shortcode in the description area.
If you mean one and the same shortcode to all the categories page, there is no option, however, there is the workaround:
1. Enable Top filters in the Theme Settings > Shop > Shop filters;
2. Enable Shop filters area always opened;
3. Shop filters content type should be set Custom content;
4. You can choose the HTML block with the content from the Shop filters custom content drop-down.
This content would appear on the shop page and in all the category pages. If you do want to show this content on the shop page we can hide it with the custom CSS on this page.
If you have any questions please feel free to contact us.
Best Regards
.
