how to show a custom taxonomy as dropdown in wordpress?

Question

I want to show a custom taxonomy in the name of custom_tax in a plugin option page as dropdown that user can select terms of taxonomy. I know that I can use wp_dropdown_categories() but I don't want show the terms of category taxonomy. I'm going to show my custom taxonomy terms as dropdown. Is there any function to do that? or no how can I do that?

Answer 1

wp_dropdown_categories() has the taxonomy parameter, which defaults to category, but can be used to retrieve custom taxonomies. Exemplary usage:

wp_dropdown_categories([
  'taxonomy' => 'custom-taxonomy-name'
]);

Answer 2

get_terms() function should help you. An example:

$terms = get_terms( array(
    'taxonomy' => 'custom_tax',
) );
