Simple plugin to display categories in any post or page with a shortcode. It’s basically a shortcode API interface to the <a href="https://developer.wordpress.org/reference/functions/wp_list_categories/" rel="nofollow ugc">wp_list_categories</a> WordPress function. This means given any of the <a href="https://developer.wordpress.org/reference/functions/wp_list_categories/#parameters" rel="nofollow ugc">parameters</a> accepted by the function, you can pass it in as a shortcode parameter to the <code>categories</code> shortcode.
Usage:
<pre><code>[categories orderby=count]
</code></pre>
Will display links to all the categories and order them by number of posts in each category.
You can also list tags or any other WordPress taxonomy. You need to pass a value to the <code>taxonomy</code> parameter. For example to list tags: <code>[categories taxonomy=post_tag title_li="Tags"]</code>. 
By default, the usage shows:
<ul>
<li>No link to all categories</li>
<li>Sorts the list of Categories by the Category name in ascending order</li>
<li>Displayed in an unordered list style</li>
<li>Does not show the post count</li>
<li>Displays only Categories with posts</li>
<li>Sets the title attribute to the Category Description</li>
<li>Is not restricted to the child_of any Category</li>
<li>No feed or feed image used</li>
<li>Does not exclude any Category and includes all Categories</li>
<li>Displays the active Category with the CSS Class-Suffix ‘ current-cat’</li>
<li>Shows the Categories in hierarchical indented fashion</li>
<li>Display Category as the heading over the list</li>
<li>No SQL LIMIT is imposed (‘number’ => 0 is not shown above)</li>
<li>Displays (echos) the categories</li>
<li>No limit to depth</li>
<li>All categories.</li>
<li>The list is rendered using a new walker object of the the Walker_Category class</li>
</ul>
See <a href="https://developer.wordpress.org/reference/functions/wp_list_categories/" rel="nofollow ugc">wp_list_categories</a> for usage.
<h3>Markup and Styling of Category Lists</h3>
Taken from the <a href="https://codex.wordpress.org/Template_Tags/wp_list_categories#Markup_and_Styling_of_Category_Lists" rel="nofollow ugc">wp_list_categories official documentation</a>.
By default, wp_list_categories() generates nested unordered lists (ul) within a single list item (li) titled “Categories”.
You can remove the outermost item and list by setting the title_li parameter to an empty string. You’ll need to wrap the output in an ordered list (ol) or unordered list yourself (see the examples above). If you don’t want list output at all, set the style parameter to none.
You can style the output with these CSS selectors :
<pre><code>li.categories { ... } /* outermost list item */
li.cat-item { ... }
li.cat-item-7 { ... } /* category ID #7, etc */
li.current-cat { ... }
li.current-cat-parent { ... }
ul.children { ... }
</code></pre>
For instance, you can remove the bullet points next to each category with:
<pre><code>.cat-item {
 list-style-type: none
}
</code></pre>
<h3>Show categories list in columns</h3>
For outputting the list into columns, you can use <a href="https://www.w3.org/TR/css-multicol-1/" rel="nofollow ugc">CSS’s multicolumns</a>. Since by default the list is printed as an unordered list with the “categories” class, you can add this to your CSS:
<pre><code>.categories{
 column-count: 5;
 column-gap: 50px;
}
</code></pre>

List categories

Thanks for publishing this little plugin. I ended up taking the code and integrating it into a custom solution but the plugin is well put together and pretty powerful.
Some better docs would help make it more useful for folks.
Thanks for making this available!

The Admin Menu Tree Page View plugin adds a tree-view layout to all your pages – directly accessible in the admin menu. This way, all your content will be available with just one click, no matter where you are in the admin area.
You can also add posts, pages and custom post types directly in the tree and you can quickly find your pages by using the real-time search box.

<h4>Top features</h4>
<ul>
<li>Change the order of your pages with drag-and-drop</li>
<li>View all your pages – no matter where in the admin you are</li>
<li>View the hierarchy (parent/child relationship) of your pages</li>
<li>Add pages directly after or inside another post – no need to first create the post and then select the parent</li>
<li>Adds link to view a public post type directly from the admin menu – no need to first edit the post and then click the view link</li>
</ul>
Works perfectly in WordPress installations with lots of pages in a tree hierarchy.

Admin Menu Tree Page View


The screenshots for this plugin show that you can access the tree of pages by going to a special page in the admin menu. But that is not what happens. Instead, this plugin adds a full list of all pages to the admin menu itself, under Pages. It's too long, it's a mess, and I can't use it. I thought this would be a good replacement for the still-working-but-apparently-abandoned CMS Tree Page View, but it is not. I'll be going back to that plugin instead.


Screenshots are not accurate

Get a tree view of all your pages directly in the admin menu. Search, add, edit, view, re-order – all is just one click away!
