title: Mat-Nav-List horizontal instead of vertical?
body: <p>How do I make the following horizontal instead of the (apparent default) of vertical?  It is located within navigation.component.html within my Angular 5.2.7 application that was generated via Angular-CLI 1.7.2.  The documentation link included in the comment does not discuss how to layout a Material navigation bar horizontally.</p>
