[wp-hackers] Adding tabbed entry panels to the Post/Page Edit Form

Actually, all that extra code is special cases for the category
handling and such. To make tabs there's only one line of javascript to
do it:
var categoryTabs = jQuery('#category-tabs').tabs();

That's literally it. jQuery makes it easy.

jQuery's tabs method basically takes the ID of a UL, and makes each LI
element in it into those tabs. The LI elements contain A links to DIVs
holding the content of the tabs, and the name of the links is used for
the names of the tabs.

Here's the category tabs UL:
<ul id="category-tabs">
	<li class="ui-tabs-selected"><a href="#categories-all"
tabindex="3"><?php _e( 'All Categories' ); ?></a></li>
	<li class="hide-if-no-js"><a href="#categories-pop"
tabindex="3"><?php _e( 'Most Used' ); ?></a></li>

As you can see, it has the LI's with the links in it, and those links
name a couple of DIVs: #categories-all and #categories-pop. Here's
those DIVs, right below that. Note how one of them defaults to
"display:none", so that it doesn't show up. Only the default tab
should show up, by default. The jQuery javascript manipulates the
display setting to show the tabs as needed.
<div id="categories-pop" class="ui-tabs-panel" style="display: none;">
	<ul id="categorychecklist-pop" class="categorychecklist form-no-clear" >
		<?php $popular_ids = wp_popular_terms_checklist('category'); ?>

<div id="categories-all" class="ui-tabs-panel">
	<ul id="categorychecklist" class="list:category categorychecklist
		<?php wp_category_checklist($post->ID, false, false, $popular_ids) ?>

That is pretty much all there is to creating working Tabs.
