Show only 1 category instead of all

Hi there,

are you using RankMath primary categories ?
If so read this topic:

You can then edit the Query Loop block, and where you have the Buttons block displaying the list of terms, replace that with a GB Headline Block and add in the Shortcode created from the link above.
