A few items we saw while trying out the different configs for the mobile menu in GP.
1) The search terms overflow on top of the search close icon. It would be great to have them constrained to the left of the search icon. Could also consider floating the search close icon all the way to the right when the search input is toggled open.
2) When the menu icon is toggled open, it would be great to have it toggle closed automatically when the search icon is selected to toggle open. That would help prevent user confusion between search results and menu items when using a live search box.
3) Have you thought about offering the option to move the search bar into the menu like Apple’s mobile menu?
Thanks for considering the above.
