I am trying to create a simple header that includes and image logo to the right and the main menu in the middle and a phone number on the right. I'm trying the click and drag in T4 Pager builder. I'm struggling to understand why the menu in the header disappears in Medium Screen display. If this is responsive there should be a hamburger menu for smaller screen sizes, right? I'm playing around with Header 01 with no understanding. Please help. Thank you.
