title: Order Categories by a custom order in wp_dropdown_categories
body: <p>I use the <code>wp_dropdown_categories( $args )</code> function to show/select certain categories. The default-setting shows the category titles in the drop-down-menu-list alphabetically <code>('orderby' =&gt; 'name')</code>. </p>
  
  <p>Because I my site has an event list, I have 7 categories, one each day i.e. "Monday", "Tuesday", .... "Sunday". </p>
  
  <p>Because of <code>'orderby' =&gt; 'name'</code> these categories are ordered alphabetically:<br>"<em>Dienstag</em>" (Tuesday), "<em>Donnerstag</em>" (Thursday) etc. </p>
  
  <p>I want to order/show them in the right sequence for days of the week, i.e. Beginning with "<em>Montag</em>" (Monday) and ending with "<em>Sonntag</em>"(Sunday). </p>
  
  <p>How can I specify a custom order for this?</p>
