Can I change the order of the items in a filter?
There are several ways to change the order of the WooCommerce Product Filters filters and the items within each filter.
Re-ordering the filters within a group
Drag and drop the sort icons to re-order the filters within a group. This changes the order of the filters as they appear on the front end of your website.
Re-ordering the options within a filter
You may also wish to change the order of the options that appear within each individual filter. For example, if you have created a filter using the 'Size' attribute then you may want to order the attributes in size order instead of alphabetically.
Attributes are ordered based on the option selected under the “default sort order” setting:
Category filters are ordered using the same order that you can set via drag and drop under Products → Categories in the WordPress admin.
