This plugin creates a widget to display and link to WooCommerce products by category in a dropdown menu. Visitors to your site will have one-click access to products in your sidebar (or other widgetized areas) without valuable real estate being used up by a regular products list.
Plugin options include the abilities to:
<ul>
<li>display all products or just products in a single category</li>
<li>sort by product name, price, total sales, number of reviews, date published, date last modified, or random</li>
<li>limit the number of products shown</li>
</ul>
This plugin is also compatible with the <a href="https://wordpress.org/plugins/post-types-order/" rel="ugc">Post Types Order</a> plugin, so you can also sort by your own customized menu order if desired.
With these options you can use this plugin for a variety of uses. You could use multiple instances of the widget to have product dropdowns for each of your categories; you could display the top 5 most frequently bought products in a specific category; you could display the top 20 most reviewed products in your entire store or just in a specific category; and so on.
Note
For sites with a very large number of products, it is not recommended that you display all products in a single dropdown because it would be both heavy on server resources and also just be difficult to use.
