React router V6 <NavLink to="/" /> is always active

I have defined a few routes:

const MainRoutes = {
  path: "/",
  element: <MainLayout />,
  children: [
    {
      index: true,
      element: <DashboardDefault />,
    },
    {
      path: "werknemers",
      element: <Werknemers />
    },
    {
      path: "verzuimdossiers",
      element: <Verzuimdossiers />
    }
  ],
};

My <MainLayout /> contains the Sidebar, Header and Outlet. In my Sidebar, I have a few <NavLinks/> like so:

<NavLink exact to="/" className={({ isActive })=> (isActive ? `active ${LINK_CLASSES}` : `inactive ${LINK_CLASSES}`)}>
  <span>Dashboard</span>
</NavLink>
<NavLink to="werknemers" className={({ isActive })=> (isActive ? `active ${LINK_CLASSES}` : `inactive
  ${LINK_CLASSES}`)}>
  <span>Werknemers</span>
</NavLink>
<NavLink to="verzuimdossiers" className={({ isActive })=> (isActive ? `active ${LINK_CLASSES}` : `inactive
  ${LINK_CLASSES}`)}>
  <span>Verzuimdossiers</span>
</NavLink>

However, my <NavLink/> for the root "/" is always active. The other 2 work just fine. If I am on "/werknemers" I do not want the Dashboard route to be also active…

What am I missing here?

>Solution :

In React Router you were using exact property to exactly match the URL in the browser. However, this only works in V5. In V6, they have changed it to end instead. So you have to do something like this:

<NavLink end to="/messages">Link</NavLink>
