could u update the code

 <SidebarContext.Provider value={{ expanded }}>
          <ul className="flex-1 px-3 overflow-y-auto">{children}</ul>
        </SidebarContext.Provider>

I am making the ul overflow-y-scroll but it also start scrolling tooltip on x-axis
what could be the problem? all other code is same

I just created a react app added the first thing is this.. it takes the full screen. Should I add something below it so it doesn't take full width ?

Is their a way to fix the over text that always goes on 2 lines when we have multiple words ?

To fix the FULL SCREEN issue add w-fit to nav element.

<nav className="h-full w-fit flex flex-col bg-white border-r shadow-sm">

When adding the property overflow-y-auto to enable scrolling, the module names no longer appear when the sidebar is collapsed and the mouse hovers over a module. How can I resolve this issue without modifying the property?

so guys i'm new to react ,but why there's nothing on the sidebar?
