Inbound Horizons

Simple Dropdown Filter by Category for Woocommerce automatically adds a dropdown on your shop catalog page that allows you to instantly filter products by WooCommerce product categories. The dropdown will show up on the shop page, product archive page and product tag page. It shows a product count per each category by default. The plugin currently supports only selecting a single category to filter.
The dropdown filter buttons shows up to the right of the native WooCommerce “sort by” dropdown and uses native WooCommerce component code.
<h4>Features and Extras</h4>
You can choose to manually exclude certain categories to show up in the dropdown filter if you do not want users to filter by those categories.
You can toggle off or on showing product counts by category or showing empty categories in your shop.
You can set custom CSS classes for styling the button to match your theme, and even apply custom CSS directly to the plugin from the back end settings panel.
It will work with nested parent/child categories you create in WooCommerce and display the child categories underneath the parent in your dropdown menu when users select a category.

<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>
