Glad to see people using my burgers, thanks for the heads up
So here is what i do personally, and probably what you should do to keep full control.
Hide you navbar desktop for tablet and lower
Drag a new container hidden on desktop but displayed on tablet and lower
Set it to relative
Drag a new div inside you container, put height, absolute top
Put Initial apparence on the new div on Y of minus your height (here 400px)
Add a new div in container with your burger inside : Absolute top right, Z index high
Finally set a new interaction on click on burger
On click, affect different element ->
Move to origin on first click.
On second click move back Y -400px
And there you have it.
Put your links inside and everything should be fine
Of course the idea is :
Do whatever you want with the interaction, make it come from left/right, opacity, bouncing whatever you want.
