HI,
Thank you for your answer it's better because it works under firefox but not under chromuim where I was testing. Pictures will help, I hope. a conflict ?
a) If I reduce the size of the browser window and click on 1), I see the full menu corresponding to the main menu!
b) In desktop mode, if I click on 2) nothing happens!
c) in both cases, I have the off-canvas module that appears on the top left!
I do not have the desired operation on chromuim
In general, what I want is
1/ a mobile menu that displays some aliases of the main menu by clicking on 2)
2/ if possible a sidebar with a text module that appears by clicking on 1)
3/ no appearance of the off-canvas module on the top left
4/ no sandwich menu at the same time in mobile mode
Regards
