<div class="w3-container">
  <h2>Navigation Bar with Dropdown</h2>
  <p><strong>Note:</strong> When the dropdown menu is "open", the dropdown link gets a grey background color to indicate that it is active. To override this, add a w3-hover-color class to both the "dropdown" container and the dropdown button:</p>
  <p><strong>Tip:</strong> If you want a dropdown symbol next to the dropdown text, add a suitable icon:</p>

<div class="w3-bar w3-light-grey">
    <a href="#" class="w3-bar-item w3-button">Home</a>
    <a href="#" class="w3-bar-item w3-button">Link 1</a>
    <div class="w3-dropdown-hover w3-hover-orange">
      <button class="w3-button w3-hover-orange">Dropdown <i class="fa fa-caret-down"></i></button>
      <div class="w3-dropdown-content w3-bar-block w3-white w3-card-4">
        <a href="#" class="w3-bar-item w3-button">Link 1</a>
        <a href="#" class="w3-bar-item w3-button">Link 2</a>
