Hello,

You can include items belonging only to a certain (or multiple) categories by entering the portfolio category slugs in page options

if you have problems with it send us wp admin access in a private comment so we can have a look

Hi Bernd,

I see what you mean, however this requires a bit of a custom work, because you can apply a category filter to portfolio page templates however the portfolio navigation is for all items.

We can make the change for a small fee or we can give you guidelines on what and where to change

Hello Bernd,

Portfolio navigation is implemented in project_navigation_section.php and there you will see two functions previous_post_links and next_post_link

https://developer.wordpress.org/reference/functions/next_post_link/

you need to specify via parameters that you want to navigate within the same category

the category parameter is 'portfolio_category' (the taxonomy for the custom post type antro_portfolio)

and $in_same_term is true

because of the navigation loop, there is an extra step in /include/hooks-config.php, functions antro_prev_post_link and antro_next_post_link, the query that selects first portfolio item, reversing the loop

https://prnt.sc/17svqdn

so I think the trick there is to get the current taxonomy terms of the current post and assign it as parameters to the WP_Query:
