I’m trying to display directly from the return of my relational tax field the name of the tax selected. I’m need to use this with visual composer “postgrid”. I can add a acf field in the template but by default the field return the ID or an Array.
ACF only stores the term ID in the DB and this is why the ID is shown. Are you trying to use a shortcode to show the term? This is an advanced field. You need to check with the creator of what you’re using to display the fields how you would go about doing what you want to do and if they offer any hooks you can use to add filters.
