Well I just needed the same thing as Jessica and the simplest way to do this is by adding the condition “wp_is_mobile()” to your “responsive-menu.php” file in the plugin folder.
Should look like this then:
/* 4.1 Display Responsive Menu on Site ============= */
if( !is_admin() && wp_is_mobile()) :
wp_is_mobile() is a funtion in your wp-includes/vars.php to detect if the viewer has a mobile device or not.
There are some plugins for further detection like is_phone() is_tablet() is_android() etc. referring to this article.
@peter I really love your plugin and think it would be great if you add at least the option with wp_is_mobile(), as it is given from wordpress 🙂
