Add filter to change wp_dropdown_categories default arguments

[jignashu]

We can add new filter on wp-includes/category-template.php file.
Function name : wp_dropdown_categories($args)
in this function, we can add one filter to change the default argument values.

Hi there, welcome to WordPress Trac! Thanks for the ticket.

Could you share a use case for this filter?

Just noting that wp_dropdown_users_args filter was introduced in [34692] / #19867.

At a glance, it would probably make sense to do the same for wp_dropdown_categories() and wp_dropdown_pages().

Maybe for wp_dropdown_languages() too, but it's mostly used in the admin, so I guess I'd skip it for now, unless there's an actual use case for a filter there.

Yes, we can add filter on wp_dropdown_pages(), wp_dropdown_languages() too.

The scenario is nothing but if some plugin calling those functions and not added filter on their plugins to change the arguments then we can use WordPress default filter to change those values.
