How to use your own widget icon in the WordPress Widget customizer

In developing deeper integration with the Customizer functionality of WordPress, I wanted to use a custom icon for my IDX+ plugin’s widgets.

By default, WordPress defines a list of icons using their dashicons icon set and tries to guess the best icon for your widget based on the CSS class of your widget.

Check out the CSS in customize-widgets.css starting on line 415.

For instance, if your widget’s CSS class contains “music”, “radio”, or “audio”, you will have the format-audio dashicon applied to your widget.

How to change the widget icon

Using Dashicons

Note: In order to choose a new icon, go to the Dashicons website and click on the icon you want to use, then click on the “Copy CSS” link to get the correct CSS content value.

#available-widgets [class*=YOUR_CSS_BASE] .widget-title:before{
    content: "\f217"; /* <-- replace this value */
}

Using your own icon font

#available-widgets [class*=YOUR_CSS_BASE] .widget-title:before{
    font-family: idx-plus!important; /* <-- replace this value */
    content: 'd'; /* <-- replace this value */
}

If you want the icon to change color when it’s hovered over, use the following code:

#available-widgets [class*=YOUR_CSS_BASE]:hover .widget-title:before{
    color: #7da838!important; /* <-- replace this value */
}

I hope this helps!
