Razorfrog Web Design

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.

The wishlist is one of the most powerful and popular tools in an ecommerce shop. Thanks to the wishlist, users can:
<ul>
<li>Save their favourite products, find them quickly and easily at a later time and buy them.</li>
<li>Share the wishlist with relatives and friends for Christmas, birthdays and similar occasions so they can buy them one of the products from the list.</li>
<li>Share the wishlist on social networks and get indirect advertising for your store.</li>
</ul>
This means that you’ll be able to loyalise customers, push them to buy and attract new customers any time a wishlist is shared. Not bad for one plugin only, don’t you think?
Our YITH WooCommerce Wishlist has more than 900,000 active installations and that’s why it’s the most popular wishlist plugin ever.
To celebrate this record and say thanks to all the plugin users, we’ve decided to release a new 3.0 version that has improved the design tremendously and added many new options.
If you like the new design, please, leave a review to help the plugin grow!
