Collapsing navbars

Here's my code:

<nav class="navbar navbar-inverse">
  <div class="container-fluid">
    <div class="navbar-header">
      <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#myNavbar">
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </button>
    </div>
    <div class="navbar" id="myNavbar">

I was super excited that the navbar works now, only to be crushed when the dropdowns stopped working. Any suggestions?
