The menu appears correctly on desktop, but on mobile devices, the items are cut off and incomplete. This is causing a significant user experience issue and affecting my store’s conversion rate.
My store is : Website. ( please see it on mobile )

I have attached a screenshot of the menu issue for your reference.

Hi there, @AzizBOUTALEB .

Welcome to the Shopify Community, and thanks for posting your question.

I had a chance to view your website on both desktop and mobile. When clicking into the main menu navigation on mobile, I can see that the menu items are cut off on the right-hand side.

To gather a bit more context on the issue, are you able to provide information on the following:

  • What theme are you currently using?
  • Have there been any changes made to your themes code?
  • When did the issue first start?
  • Have you recently installed any new apps?
  • Are you able to replicate the issue in a fresh theme by previewing it on mobile?

I can’t believe it, your solution worked, you are truly a genius, I will never forget your help, thank you very much, thank you very much, you are a great person
