react router dom nested routes

<Route path="/menu" element={<Menu />}>
  <Route path="featured" element={<Featured />} />
  <Route path="previous" element={<Previous />} />
  <Route path="favourites" element={<Favourites />} />
  <Route path=":categoryId/:menuId" element={<MenuDetail />} />
</Route>

<Route path="/menu" element={<Menu />} />
<Route path="/menu/featured" element={<Featured />} />
<Route path="/menu/previous" element={<Previous />} />
<Route path="/menu/favourites" element={<Favourites />} />
<Route path="/menu/:categoryId/:menuId" element={<MenuDetail />} />

I thought these two codes do the same thing but found out they do not. First one being the nested routes under menu route, and the second is just regular routes. Apparently the second code is what I want it to do.

The first one, when I go to

They all give me Menu component, which I do not want. So I had to try the second code to achieve what I wanted.

But aren't they the same?

If I were to achieve what I want using the nested routes, how should I write this code?

The first example the Menu component is rendered as a layout route. Layout routes components should also render an Outlet component for their nested routes to also render out their element content. If only Menu is being rendered then I suspect you are missing the Outlet.

That said, if you wanted to make the two snippets the same then you'd render Menu as an index route of a layout route rendered on "/menu". When a layout Route is not passed an element prop it renders just an Outlet by default.

Example:

<Route path="/menu">
  <Route index element={<Menu />} />
  <Route path="featured" element={<Featured />} />
  <Route path="previous" element={<Previous />} />
  <Route path="favourites" element={<Favourites />} />
  <Route path=":categoryId/:menuId" element={<MenuDetail />} />
</Route>

Which is equivalent to rendering them all individually unnested with fully qualified route paths.

<Route path="/menu" element={<Menu />} />
<Route path="/menu/featured" element={<Featured />} />
<Route path="/menu/previous" element={<Previous />} />
<Route path="/menu/favourites" element={<Favourites />} />
<Route path="/menu/:categoryId/:menuId" element={<MenuDetail />} />
