Dynamically adding menu item won't toggle in sidebar-nav to Sb Admin 2
Question
I'm new to bootstrap and JQuery. I am having a problem with SB Admin 2 bootstrap. I've stripped down an example (Dashboard) page and added a menu item to the sidebar-nav dynamically.
The problem is that the new menu item won't toggle / collapse.
Below is a snippet of the html of side menu which works.
<nav class="navbar navbar-default navbar-static-top" role="navigation" style="margin-bottom: 0">
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="#" id="navbar_brand">SB Admin v2.0</a>
</div>
<!-- /.navbar-header -->
<ul class="nav navbar-top-links navbar-right">
<li class="dropdown">
<a class="dropdown-toggle" data-toggle="dropdown" href="#">
<i class="fa fa-user fa-fw"></i> <i class="fa fa-caret-down"></i>
</a>
<ul class="dropdown-menu dropdown-user">
<li>
<a href="login.html"><i class="fa fa-sign-out fa-fw"></i> Logout</a>
</li>
</ul>
<!-- /.dropdown-user -->
</li>
<!-- /.dropdown -->
</ul>
<!-- /.navbar-top-links -->
<div class="navbar-default sidebar" role="navigation">
<div class="sidebar-nav navbar-collapse">
<ul class="nav" id="side-menu">
<li>
<a href="index.html"><i class="fa fa-dashboard fa-fw"></i> Dashboard</a>
</li>
<li>
<a href="#"><i class="fa fa-files-o fa-fw"></i> Sample Pages<span class="fa arrow"></span></a>
<ul class="nav nav-second-level">
<li>
<a href="blank.html">Blank Page</a>
</li>
<li>
<a href="login.html">Login Page</a>
</li>
</ul>
<!-- /.nav-second-level -->
</li>
</ul>
</div>
<!-- /.sidebar-collapse -->
</div>
<!-- /.navbar-static-side -->
</nav>
To dynamically add a new menu item I've added a click event handler as below.
$("#navbar_brand").click(function(){
$("#side-menu").append('<li><a href="#"><i class="fa fa-files-o fa-fw"></i> TEST Pages<span class="fa arrow"></span></a><ul class="nav nav-second-level"><li><a href="blank.html">Blank Page</a></li><li><a href="login.html">Login Page</a></li></ul></li>');
});
The new menu item appears but doesn't toggle as the original Samples Pages menu. Could somebody help?
TIA

Hard to tell exactly what the #side-menu functionality is without being able to look inside the JS scripts you're using, but you need to pay attention to the order in which JavaScript works. This is what your browser is doing:
- Reading the HTML document.
- Loading and executing all .js files. In here, your plugin is looking for
#side-menuand applying functionality to its 2 existing<li>child elements. - Upon clicking on
#navbar_brand, it's adding a 3rd<li>child to#side-menu, but this one never has any functionality added to it, since that took place in step 2.
You have 2 options:
- Look into the plugin's features, and see if you can initiate it again after you've added the 3rd
<li>child. - Have all 3
<li>s built into the HTML document, but havedisplay: nonein the CSS for the 3rd one. Once you click on#navbar_brandyou can show it by changing its style todisplay: blockor whatever you wish.
