This is a lightweight plugin to add a dynamic sub-menu to a WordPress menu. It is known to work with <a href="https://wordpress.org/plugins/nav-menu-roles/" rel="ugc">Nav Menu Roles</a>. 
Caution is indicated if trying to use it with a theme, menu plugin, or anything that makes significant changes to how the WordPress menu is handled. It can insert a 
single sub-menu using any public taxonomy, such as catagories, tags, as well as woocommerce product categories or tags. A seperate sub-menu for bbPress forums is 
available.
<h3>Setup</h3>
The settings screen can be reached either via the settings link on the ‘Installed Plugins’ page, or via the ‘Dynamic Taxonomy’ option on the ‘Appearence’ menu.
The settings screen will enable you to control things like:
<ul>
<li>Which menu the sub-menu is added to, default is the primary menu.</li>
<li>Which taxonomy is displayed, default is categories.</li>
<li>The title used for the sub-menu, default is ‘Articles’.</li>
<li>The position in the menu, default is to appear as the second menu item.</li>
<li>The maximum number of items on the submenu, default is 7.</li>
<li>Listing order of the sub-menu items, available is Term Name, Post Count (default), and Term ID.</li>
<li>Which terms to exclude from the list, default is none, works for Category only (for now).</li>
<li>Whether to include an item count on the sub-menu, default is yes.</li>
<li>Items can also be limited by the count, ie: nothing with a count of less then N. Default is 0.</li>
</ul>
The plugin also allows you to show bbPress forums, although those options are limited to:
<ul>
<li>Which menu to add the forum list to.</li>
<li>What position in the menu to take, default is the third menu item.</li>
<li>What text to use as the menu option, default is ‘Forums’.</li>
</ul>

Dynamic Taxonomy Menu Items

Add a dynamic taxonomy list to your WordPress menus.

This plugin lets you specify a header image for each post, page, custom post type or archive page individually, from your default headers and custom headers.
It adds a meta box in the post edit screens with the header selection and a settings field in the edit profile and each taxonomy edit screen. 
If no specific header is specified for a post it will fall back to the default selection. 
There is no change of template files necessary as this plugin hooks in the existing WordPress API to unfold its magic.
Thanks to Erik T. for the idea to this plugin!
