Bootstrap 4 navbar not showing [duplicate]

Answer 1

It's not showing because the Bootstrap 4 classes and structure are different from Bootstrap 3.

Also important:

When loading JavaScript files, you must load jQuery first, then Popper.js and then Bootstrap.js.

This is what a Bootstrap 4 navbar looks like:

  Navbar
  
    
  

  

    

      

        Home (current)
      
      

        Link
      
      

        
          Dropdown
        
        

          Action
          Another action
          

          Something else here
        
      
      

        Disabled
