[Plugin: Co-Authors Plus] Create coauthors dropdown list form with submit

Hello,

I found the dropdown users function in the WordPress codex:

<?php wp_dropdown_users( $args ); ?>

But it doesn’t work in conjunction with the coauthors plugin. The following code gets very close:

<li id="users">
 <h6><?php _e('Article Authors:'); ?></h6>
   <form action="<?php bloginfo('url'); ?>" method="get">
   <?php wp_dropdown_users('exclude=1,2,26,11'); ?>
   <input type="submit" value="Show" />
   </form>
</li>

But it doesn’t use custom urls, i.e. it goes to a place like, https://monthlyreview.org/_beta01/?user=17 instead of using “/author/[authorname]/. Has anyone rewritten this function for coathors plus?

Thanks.

My custom url
