Loop to display ONLY custom taxonomy parent information [closed]

I believe this has already been answered perfectly in How can I get only parent terms?.

The solution is to set 'parent' => 0 when querying terms with get_terms() or WP_Term_Query. The example from that question looked like this:

$myterms = get_terms( array( 'taxonomy' => 'taxonomy_name', 'parent' => 0 ) );

You can easily loop over the result and in it retrieve the fields you mentioned.

Hope that helps! If you need more guidance, please let me know and I can look into expanding my answer a bit.
