Content template for loop of CPT grouped by custom taxonomy term

Hi there,

Is there any estimated date for the implementation of this functionality?

Do you mean adding CPT to a page?
If so, you can use the query loop block of GenerateBlocks and select the post type.
You can have multiple query loop blocks on a page.

Am I doing something wrong when I apply the content template, or is it that GP elements is not compatible with the snippet that generates the loop grouped by taxonomy?

It’s not compatible. As content template requires GP’s template while the PHP code creates its own custom template.

If you want to use the query loop block on a static page to achieve this, this topic is pretty similar:

The code in your case would be something like this, changemy-termto the CSS class you add to the query loop block > grid, change custom_tax to your taxonomy and change custom_tax_term_A to your term.

add_filter( 'generateblocks_query_loop_args', function( $query_args, $attributes ) {

    if ( ! empty( $attributes['className'] ) && strpos( $attributes['className'], 'my-term' ) !== false ) {

        $tax_query = array(
            array(
                'taxonomy' => 'custom_tax',
                'field'    => 'slug',
                'terms'    => 'custom_tax_term_A',
            ),
        );

        $query_args = array_merge( $query_args, array(
            'tax_query'  => $tax_query,
        ) );
    }

    return $query_args;
}, 10, 2 );
