The Hustle Popup shortcode enables the display of specific popup modules on your WordPress site. It accepts parameters like ‘id’, ‘type’, and ‘css_class’ to customize the popup display. . The ‘id’ parameter is crucial as it specifies the module to display. The ‘type’ parameter can be ’embedded’ or ‘social_sharing’, affecting the popup’s behavior. The ‘css_class’ parameter allows for additional styling. If the shortcode is misconfigured or the specified module is inactive, it returns an empty string.
