Using The Primary Menu As The Mobile Header Menu

This feature is totally optional and certainly not ideal in all cases where a Header Menu is in use, but often times it's useful to use a Header Menu while still having it turn into a Mobile "hamburger menu" when displaying on mobile devices. In such cases check the box in Dynamik Design > Responsive > Show/Hide Options > "Use Primary Menu as a mobile version of the Header Menu" and then be sure to go to Appearance > Menus in your WP Dashboard and set a Custom Menu as your "Primary Navigation Menu".

The result of combining the above mentioned option and activating your "Primary Navigation Menu" will be that your Primary Menu will be hidden from view except when the mobile menu displays, in which case the Header Menu will then be hidden. This ends up appearing to seamlessly swap menus so it looks like your Header menu just turns into the mobile menu.
