How to add "sub-element"?

Question

React

Good evening. Tell me how it is done that "Navbar.Brand" is added to a certain place in the "Navbar".
Like this:

<Navbar bg="dark" variant="dark" expand="lg">
  <Navbar.Brand href="#home">{ props.siteName }</Navbar.Brand>
  <Navbar.Toggle aria-controls="NavbarContent" />
</Navbar>

Answer 1

Understood. Those "sub-elements" are props.children.
