Answer 1

You can use this javascript to add active class based on current url please try it

<script type="text/javascript">
    $(document).ready(function () {
        var url = window.location;
        $('ul.nav a[href="'+ url +'"]').parent().addClass('active');
        $('ul.nav a').filter(function() {
             return this.href == url;
        }).parent().addClass('active');
    });
</script>

Can't you just use this replacing your <a> tags. This will match the current uri string, with the links href attribute. If it matches, it add's an active class to the link. You can style the .active using you

<a href="<?php echo site_url('admin/company'); ?>" class="<?php if($this->uri->uri_string() == 'admin/company') { echo 'active'; } ?>">Company</a>

So the entire code will be.

<ul class="nav navbar-nav">
      <li><a href="<?php echo site_url('admin/dashboard'); ?>" class="<?php if($this->uri->uri_string() == 'admin/dashboard') { echo 'active'; } ?>">Dashboard</a></li>
      <li><a href="<?php echo site_url('admin/company'); ?>" class="<?php if($this->uri->uri_string() == 'admin/company') { echo 'active'; } ?>">Company</a></li>
      <li><a href="<?php echo site_url('admin/user'); ?>" class="<?php if($this->uri->uri_string() == 'admin/user') { echo 'active'; } ?>">Users Management</a></li>
      <li><a href="<?php echo site_url('admin/key'); ?>" class="<?php if($this->uri->uri_string() == 'admin/key') { echo 'active'; } ?>">Key Management</a></li>
      <li><a href="<?php echo site_url('admin/activation'); ?>" class="<?php if($this->uri->uri_string() == 'admin/activation') { echo 'active'; } ?>">Activated Devices</a></li>
</ul>
<ul class="nav navbar-nav navbar-right">

Your pages should know which menu should be set as active.

Try adding an id to your <li> and add a javascript code to your pages to set the active menu based on the ID. Example:

<ul class="nav navbar-nav">
      <li id="menu-dashboard" class="active"><a href="<?php echo site_url('admin/dashboard'); ?>">Dashboard</a></li>
        <li id="menu-company"><a href="<?php echo site_url('admin/company');?>">Company</a></li>
        <li id="menu-user"><a href="<?php echo site_url('admin/user');?>">Users Management</a></li>
        <li id="menu-key-management"><a href="<?php echo site_url('admin/key');?>">Key Management</a></li>
        <li id="menu-activation"><a href="<?php echo site_url('admin/activation');?>">Activated Devices</a></li>
  </ul>

<script>
var menuid = "menu-dashboard";
$(function() {
    $('.nav li').removeClass('active');
    $(menuid).addClass("active");
});
</script>

Pages: Add the following javascript lines to your pages

• Company page

  menuid = "#menu-company";

• User page

  menuid = "#menu-user";
