copied!<p>If you don't use the Description field of the categories, ordering can also be done by entering a number in each Description field, and subsequently use Javascript / jQuery to order based on this numbering.</p> <p>The wp_list_categories function has a <strong>use_desc_for_title</strong> argument which you can set to true:</p> <pre><code>wp_list_categories('use_desc_for_title=1'); </code></pre> <p>The category description is now set to the <code><a></code> tags's title attribute in the resulting html.</p> <p>So if you use numbers in the description field, the resulting category listing may look like this:</p> <pre><code> <ul id="category_list"> <li><a href="#" title="3">Category C</a></li> <li><a href="#" title="1">Category A</a></li> <li><a href="#" title="2">Category B</a></li> </ul> </code></pre> <p>Now you can sort the list, for example with jQuery at the document.ready event. If you use subcategories in a hierarchical way, use a recursive function like this:</p> <pre><code>$( document ).ready( function() { sort_list_recursive( $( '#category_list' ) ); } ); function sort_list_recursive( parent ) { var lst = parent.children( 'li' ); lst.sort( function( a, b ) { var _a = a.getElementsByTagName( 'a' )[0].title; var _b = b.getElementsByTagName( 'a' )[0].title; return _a > _b ? 1 : -1; } ).appendTo( parent ); lst.each( function() { $( this ).children( 'ul' ).each( function() { sort_list_recursive( $( this ) ); }); }); } </code></pre> <p>N.B.</p> <ul> <li>Don't use a 0 (zero) in the description field, it will be ignored and set to null</li> <li>After sorting you might want to get rid of the title attributes which are set to numbers, this can easily be done with jQuery.</li> </ul>
