For example, Having 1st Page HTML Include header Page HTML
Page 1 javascript
<script src="//code.jquery.com/jquery-1.10.2.js"></script>
<script> 
   $(function(){
     $("#header").load("Header.html");
   });
</script>
<div id="header"></div>
Header page
<a href="#" data-toggle="dropdown" class="dropdown-toggle">Booking
<span class="caret"></span></a>
<ul class="dropdown-menu">
    <li><a id="booking" href="#">New Booking</a></li>
    <li id="cancel"><a href="url">Cancellation</a></li>
    <li id="my_booking"><a href="url">My Booking</a></li>
</ul>
</li>
So my problem is, in my header page HTML I having a menu drop-down-list. During the page is loading, I am able to click the menu to drop down the list. Once the page is complete loaded to the page 1, the menu is malfunctioned and not response after I click.
