To see the bug. Open navigation menu on the collection template page. The flex alignment to center vertical is not working and the nav open / close icon disappears. You can see on this page that the navigation is not working as per the other pages. I’m pretty sure it’s a bug as there is no logical explanation for the behaviour.
Thanks for sharing being unable to have your menu interaction work as expected, as this does sound like odd behavior.
We were able to take a look at your project, and the issue may be related to the display settings selected within your interaction: Image 2019-01-18 at 3.21.47 PM
The additional z-index issue may also be related to the interaction as well.
Hopefully, this was helpful. Feel free to let us know if this is helpful, or if you have any additional questions.
Thanks for the quick reply. The display settings is set to Flex in the project. I can’t replicate the screenshot and the issue still persists. The navigation works fine for all other pages and there is no differences in the set up. What is the z-index issue?
