Header's navbar burger seems to be broken

[huguesdevimeux]

Hello,

While trying to use elements, I struggled to make the "hamburger" style button (called navbar toggle mobile, I think) work (reference, here is the atom ).

The hamburger button correctly appears when the viewport is of the appropriate size, but clicking on it outputs no action (when I would expect it to show the menu content). You can reproduce this behaviour directly on the docs, here). Copy and pasting the code to a local file outputs the same result.

Interestingly, the basic_page example has the correct behaviour. I wasn't able to track down what was different code-wise, as it appears to be built on the fly.

Am I missing something ? Do I have to manually select which options should be displayed by the hamburger ? I assumes these were automatically detected with the menu_item_<id> id.

Thanks in advance for your help !
