The Shop Ajax tags dropdown allows customers to sort products based on tags instead of variations. For example: 
Show all products with tag “Tshirt” or show all products with tag “Jumper” and “Jersey”.
This plugin still needs some development, but if you just need a basic AJAX tag widget it will do. 
We hope to release and updated version in a couple of weeks which works better.
This plugin is compatible with WordPress 4.0 and WooCommerce 2.2.0-bleeding.

<h3>What you need, where you need it – and when.</h3>
For WordPress 3.8 to 6.9+ – Backward compatibile to WordPress 3.5 (see <a href="https://wordpress.org/extend/plugins/admin-menus-fixed/other_notes/" rel="ugc">Other Notes</a>) 
Works with: <a href="https://wordpress.org/extend/plugins/ozh-admin-drop-down-menu/" rel="ugc">Ozh’ Admin Drop Down Menu 3.6+</a> and <a href="https://wordpress.org/extend/plugins/ag-custom-admin/" rel="ugc">AG Custom Admin 1.2.5+</a>
Admin Menus Fixed Three Ways: As a companion to Ozh’ Admin Drop Down Menu AND/OR AG Custom Admin OR Standalone (WordPress 3.5-3.7)
<ul>
<li>
New in v1.4 Now Responsive down to phone sizes. Ozh’ Admin Drop Down Menu header background automatically changes to high contrast when displayed on smaller screens.
</li>
<li>
New in v1.4 Ozh’ Admin Drop Down Menu Header Gradient now wraps when the header does; improving the look and readability!
</li>
<li>
Consolidates the WordPress Toolbar and Ozh’s menu and makes them both always readily available at the top of your window; no matter where you happen to be scrolled on a long page.
</li>
<li>
Incorporates HoverIntent to chill the Toolbar drop-down menu hair trigger, so now you can overshoot Ozh’ Menu without the Toolbar menu falsely stepping on it; causing you to move away until it closes, so that you can get to what you were going for. Way easier to work this way. Fast. Efficient.
</li>
<li>
Automatically adjusts to the WordPress Toolbar display state; whether disabled by Ozh’ Admin Drop Down Menu or AG Custom Admin.
</li>
</ul>
Standalone: (Depreciated) The WordPress Devs have taken a page from this plugin’s book, pulling the concept into core by fixed-positioning the Toolbar and Admin Menus in versions 3.8+, so the plugin code is shrinking. Kinda goes against the new direction of pulling code out of core and having plugins handle the function if you want/need it, but I’m glad that the concept has been adopted; because it was long overdue. The plugin is returning to its own core purpose, that of enhancing Ozh’ Admin Drop Down Menu, and I’m OK with that. – see <a href="https://wordpress.org/extend/plugins/admin-menus-fixed/other_notes/" rel="ugc">Other Notes</a>

The WordPress Toolbar and standard Admin Menu along the left side are made fixed-position in both expanded and collapsed modes; eliminating a lot of scrolling.
