Multiple post type in one query loop

Hi there,

It will require some PHP code.

1. Add a css class to the Grid block nested in the query loop block, eg.multi-query :https://wordpress.com/support/wordpress-editor/adding-additional-css-classes-to-blocks/
2. Add this PHP code, and change this line array('post', 'page', 'cpt-slug-1', 'cpt-slug-2');to match your post types.

add_filter( 'generateblocks_query_loop_args', function( $query_args, $attributes ) {
	if ( 
        ! is_admin() &&
        ! empty( $attributes['className'] ) && 
        strpos( $attributes['className'], 'multi-query' ) !== false
	) {
        // pass meta_query parameter
        $query_args[ 'post_type' ] = array('post', 'page', 'cpt-slug-1', 'cpt-slug-2');
	}
	
	return $query_args;
}, 10, 2 );
