This plugin allows page authors to easily list any child pages of a given page by simply using a new <code>[childpages]</code> shortcode. A basic list of the children to the page you’re editing will be returned with the shortcode <code>[childpages]</code>. More-complex versions of the shortcode, as described in the Usage section, give you additional control over the output results.
<h3>Usage</h3>
The basic shortcode to get a page list is <code>[childpages]</code>. Wherever you have a need to drop of a list of child pages for the page you’re currently authoring, just enter that code in either the Visual or HTML editor. The list that results will not be shown with a title, will be one level deep, will not exclude any child pages or authors, and will be sorted by page order and then by title.
To list the child pages with a title, use the enclosing form of the shortcode, like this:
<blockquote>
[childpages]List Title[/childpages]
</blockquote>
The text between the opening and closing shortcodes will be the title of the resulting list. It is being passed to the <code>title_li</code> attribute in the <code>wp_list_pages()</code> template tag.
To change the defaults used to format the list, pass the appropriate parameters in your shortcode, like this:
<blockquote>
[childpages depth=2 sort_column=ID]
</blockquote>
The parameters you provide are passed to <code>wp_list_pages()</code>. The following parameters are supported; usage details for these parameters can be found in the WordPress Codex.
<ul>
<li><code>depth</code></li>
<li><code>child_of</code></li>
<li><code>exclude</code></li>
<li><code>echo</code></li>
<li><code>authors</code></li>
<li><code>sort_column</code></li>
</ul>

SR-ChildPages

This plugin allows page authors to easily list any child pages of a given page by simply using a new [childpages] shortcode.

Sometimes when you divide up your WordPress content into categories it all ends up in sub-categories of one or two main categories that don’t have any content themselves.
With the widget you can add a list of sub-categories even if the parent doesn’t have posts.
You can display and filter sub-categories in various ways:
<ul>
<li>Use the parent category as the widget title</li>
<li>Show post counts in bracket next to the name</li>
<li>Hide empty sub-categories</li>
<li>Add a link to the parent category to the widget title</li>
<li>Show the full sub-category tree so it include sub-sub categories and so on as well</li>
<li>Display the list as dropdown rather than as links</li>
<li>Use the first category of the current post as the parent</li>
<li>Exclude one or more sub-categories from the list</li>
<li>List the categories in reverse order</li>
</ul>

This Widget lists the sub-categories for a given category.
