Fixing a Responsive Navbar (Not bootstrap)

Question

NOTE: THE NAVBAR ISN'T IN BOOTSTRAP

I have made this Navbar responsive as you can see in the code under this, but the problem is that when screen is shorter than 950px it shows the button to which is supposed to open a menu with buttons one under another so it can fit n the screen, but it does nothing when I click on it. Am I missing code or something? Any help will be greatly appreciated.

Answer 1

use click function for li > a, it will works now...

<li>
   <a id="attr_nav">
     <i class="fa fa-bars"></i>
   </a>
 </li>

$(function() {
   var ulLi = $('nav ul > li');
  var fa = $('nav ul > li:last-of-type a .fa');
   $('nav ul').append('<ol></ol>');
  $('nav').each(function() {
     for (var i=0; i <= ulLi.length - 3; i++) {
       $('nav ul > ol').append("<li>"+ i +"</li>");
       $('nav ul > ol > li').eq(i).html(ulLi.eq(i+1).html());
     }
  });

   $('#attr_nav').click(function(){ 
    $('nav ul > li:last-of-type').parent().children('ol').slideToggle(500);

    });
});

Answer 2

Unless you have some js you didn't post where you add list items to the button you are mentioning the button you are talking about has no functionality.

<li>
   <a href="#">
     <i class="fa fa-bars"></i>
   </a>
 </li>

This is the button you are talking about and it is just an empty link with an icon.

You should add the dropdown options like this:

<li><div class="dropdownd">
 <a href="#" class="dropbtnd">
     <i class="fa fa-bars"></i>
   </a>
 <div class="dropdown-contentd">
   <a class="dropdowncontentn" href="leaderboard.php">Leaderboard</a>
   <a class="dropdowncontentn" href="partnerships.php">Partnerships</a>
   <a class="dropdowncontentn" href="contact.php">Contact us</a>
   <a class="dropdowncontentn" href="socialmedia.php">Social Media</a>
   <a class="dropdowncontentn" href="settings.php">Settings</a>
 </div>
</div> 
</li>

This will be the complete html:

<nav>
 <ul>
 <li><a href="home.php">Home</a></li>
 <li><a href="earnpoints.php">Earn Coins</a></li>
 <li><a href="getrewards.php">Get Rewards</a></li>
 <li><a href="referrals.php">Referrals</a></li>
 <li><a href="vouchers.php">Vouchers</a></li>
 <li><div class="dropdownd">
 <a href="#" class="dropbtnd">More</a>
   <i class="fa fa-caret-down"></i>
 <div class="dropdown-contentd">
   <a class="dropdowncontentn" href="leaderboard.php">Leaderboard</a>
   <a class="dropdowncontentn" href="partnerships.php">Partnerships</a>
   <a class="dropdowncontentn" href="contact.php">Contact us</a>
   <a class="dropdowncontentn" href="socialmedia.php">Social Media</a>
   <a class="dropdowncontentn" href="settings.php">Settings</a>
 </div>
</div> </li>
<li><div class="dropdownd">
 <a href="#" class="dropbtnd">
     <i class="fa fa-bars"></i>
   </a>
 <div class="dropdown-contentd">
   <a class="dropdowncontentn" href="leaderboard.php">Leaderboard</a>
   <a class="dropdowncontentn" href="partnerships.php">Partnerships</a>
   <a class="dropdowncontentn" href="contact.php">Contact us</a>
   <a class="dropdowncontentn" href="socialmedia.php">Social Media</a>
   <a class="dropdowncontentn" href="settings.php">Settings</a>
 </div>
</div> 
</li>

 <li class="thum" style="float:right;margin-right:25px;">
   <a onClick="navbar_coins_refresh.php" href="#" class="coinsnumber"><?php include 'navbar_coins.php'; ?></a>
 </li>
</ul>
</nav>

Answer 3

You have to understand in order to make your website interactive without loading a new page you will need to add some javascript to your code. Something like this could work:

HTML

<button onclick="showMobileMenu()">Show menu</button>

<div id="mobile-menu" class="mobile-menu">
  Your mobile menu here...
</div>

CSS

.mobile-menu{
  display:none;
}
.mobile-menu.show {
  display: block;
}

Javscript

function showMobileMenu() {
  var element = document.getElementById("mobile-menu");
  element.classList.add("show");
}
