Hi @E_Lugo ,
The custom code added to the custom.css file was overriding the design for mobile devices. To display the dropdown menu on a mobile device, please add the following code at the end of the ‘theme.liquid’ file.
Steps to add CSS:
Step 1: Go to Online Store > Themes > Active theme > Edit
Step 2: Search for “theme.liquid”

Step 3: Add the CSS above “”

If you require further help to add the code to your store, please don’t hesitate to reach out. If you find this information useful, a Like would be greatly appreciated. And if this solves the problem, please Mark it as Solution!
