So one thing webflow does very well is that when you change the viewing device at the top, any changes you make to the elements on the page whilst that device is selected will only take effect whilst that specified device is in use.
So, what you can do is having the NavBar as to Display: Block when it’s on Desktop and Tablet but the Burger Stack Menu (When you create it) set to Display: None when viewing on Desktop on Tablet.
Then do vice versa for when you’re viewing on Mobile.
The Display options are shown under the Layout tab on the Style panel. The last option is a line through an eye icon is Display: None.
But, I would say you can save yourself a bucket load of time by using Webflows already provided NavBar element, and just redesign it how you’d like it to look.
