There use to be a “visible on” option where you can select if you wanted “visible” on a device. i dont see it any more, it was in setting under neath the tag.
For example i want to change my nave bar to a burger icon in the ipad and mobile, and i need to make the desk top nave to disappear
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.
Just letting you know that the visibility option you remember being there was removed for good. Reasons aside you will need to use display:none for every breakpoint you want an element to be disabled on as @Martin_DSGNLAB suggested.
