The community member has a question about creating a hamburger menu. Other community members respond that there is a Sheet component that can be used for this. The community members also discuss the app, including their hope for an e-commerce option, and a question about breakpoints and how they can be customized. A community member provides a recommendation to keep the default breakpoints unless a special use case is needed.
You can change the breakpoints to whatever you like. They've picked some good defaults, though.
It will all depend on the end user, their device, resolution, magnification settings, dpi settings, etc. I'd recommend just keeping the Webstudio defaults unless you need some special use case.
