Custom popup trigger is a unique feature included in the Radio Player plugin that opens the popup player in a new window. You can set up the custom popup trigger with any buttons or element by using the element’s CSS selectors.
For example, I want the popup player to be open when users click the button. Right-click on the button > inspect elements > copy the class or ID.
Navigate to Radio Player > Settings > Popup Player Settings > add new trigger > paste class or id in the Element Selector (class preceding with a ‘.’ and ID preceding with a ‘#’) > Select Player you want to enable popup > Save changes.
Now once anyone clicks the button the custom popup trigger will open in a new window.
