Responsive navbar with dropdown not working

Tags: , , , ,



I am working on creating a responsive navbar that has a dropdown in it. Below is my code:

I have the CSS code and media queries inline for testing purpose. So it might look lengthy.

<link href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet" />
<link href="../../themes/bootstrap/starterkits/THEMENAME/css/style.css" rel="stylesheet" />
<link href="//fonts.googleapis.com/css?family=Raleway" rel="stylesheet" type="text/css" />
<style type="text/css">body {margin:0;font-family:Arial}

.topnav {
  overflow: hidden;
  background-color: #ffffff;
}

.home {
  float: left;
  overflow: hidden;
}

.topnav a {
  float: right;
  display: block;
  color: #000000;
  text-align: center;
  padding: 14px 16px;
  text-decoration: none;
  font-size: 17px;
}

.active {
  background-color: #4CAF50;
  color: white;
}

.topnav .icon {
  display: none;
}

.dropdown {
  float: right;
  overflow: hidden;
}



.dropdown .dropbtn {
  font-size: 17px;    
  border: none;
  outline: none;
  color: black;
  padding: 14px 16px;
  background-color: inherit;
  margin: 0;
}

.dropdown-content {
  display: none;
  position: absolute;
  background-color: #ffffff;
  min-width: 160px;
  box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
  z-index: 1;
}

.dropdown-content a {
  float: none;
  color: black;
  padding: 12px 16px;
  text-decoration: none;
  display: block;
  text-align: left;
}

.topnav a:hover, .dropdown:hover .dropbtn {
  background-color: #555;
  color: #D5DBDB;
}

.dropdown-content a:hover {
  background-color: #ddd;
  color: black;
}

.dropdown:hover .dropdown-content {
  display: block;
}

@media screen and (max-width: 600px) {
  .topnav a:not(:first-child), .dropdown .dropbtn {
    display: none;
  }
  .topnav a.icon {
    float: right;
    display: block;
  }
}

@media screen and (max-width: 600px) {
  .topnav.responsive {position: relative;}
  .topnav.responsive .icon {
    position: absolute;
    right: 0;
    top: 0;
  }
  .topnav.responsive a {
    float: none;
    display: block;
    text-align: left;
  }
  .topnav.responsive .dropdown {float: none;}
  .topnav.responsive .dropdown-content {position: relative;}
  .topnav.responsive .dropdown .dropbtn {
    display: block;
    width: 100%;
    text-align: left;
  }
}
</style>
<div class="panel">
<div class="topnav" id="myTopnav">
<div class="home"><a href="#"><img src="../../sites/default/files/logo_0.png" /></a></div>

<div class="dropdown">
<div class="dropbtn"><a href="#">Programs</a></div>

<div class="dropdown-content"><a href="#">Success</a></div>
</div>
<a href="#">Contact</a> 
<a href="#">Families</a> 
<a href="#">About</a> 
<a class="icon" href="javascript:void(0);" onclick="myFunction()" style="font-size:15px;">☰</a></div>
</div>
<script>
function myFunction() {
  var x = document.getElementById("myTopnav");
  if (x.className === "topnav") {
    x.className += " responsive";
  } else {
    x.className = "topnav";
  }
}
</script>

The menu contains the Home logo image at the left and 4 menu items on the right.

After the active ‘home’ link is the ‘Programs’ drop-button that should have a dropdown ‘Success’ underneath it. This dropdown is not loading correctly and the design is distorted. Any help to fix this?

Answer

You don’t need your dropdown button to be a div tag, it should be a button tag.

So change

<div class="dropbtn"><a href="#">Programs</a></div>

to

<button class="dropbtn"><a style="padding: 0px" href="#">Programs</a></button>

This should the drop-down load correctly and inline with the other items in the navbar. Hopefully this helps you get on the right track without changing most of your original code.
