This plugin allows you to get better control on how your categories are listed. It provides a widget which lets you get more options than the default WordPress category widget (show RSS, hide empty categories, etc.). Furthermore, it allows to hide the children categories and use clickable buttons to expand them. The plugin requires jQuery to be included in your theme. It degrades nicely when javascript is not available to the usual WordPress category list.

Enhanced Links

A plugin for wordpress which allows you to list your links in a sexier way. Very useful when you have a great number of links and categories.

fishdan Jsonmaker lets administrators curate a nested tree of links directly on the front end. Drop the <code>[jsonmaker]</code> shortcode onto a page, expand nodes to add children, rename or remove items inline, and fetch any branch at <code>/json/<slug>.json</code>.
Highlights
<ul>
<li>Inline “Add”, “Edit”, and “Delete” controls for administrators (capability <code>jsonmaker_manage</code>).</li>
<li>Clean JSON endpoint for each node (<code>/json/<slug>.json</code>).</li>
<li>Store either URLs or plain text values; an empty value keeps a node as a container.</li>
<li>All data persists in a single WordPress option—no custom tables.</li>
</ul>

fishdan Jsonmaker

Manage hierarchical link collections via a shortcode, edit them inline, and expose any node as JSON.
