This option is available in the premium version of the plugin.
This advanced style option allows you to assign an individual icon for each filter term (with hover / active states), as well as set custom labels. Select the Custom term icons and labels style from the Filter styles select box.
In the list of filter terms, put the chosen Font Awesome icons (or more than one icons, or even custom text) for the corresponding filter term, and adjust the label as needed. Whenever you don’t want any icon or label for a term, simply leave the corresponding field empty. Don’t forget to push the Save Changes button at the bottom of the page when finished.
Some of the icons are presented at the bottom of the section. You can copy them into the clipboard by simply clicking on them. To explore the whole variety of available icons, please visit the Font Awesome Gallery .
