Newbie needs help with jquery multiayer menu

Hello there, 

I am a beginner in java and have no idea about javascrip, but have tried my best with this,I need to create a dynamic dropdown menu from a predefined array.

Here is the array I need in javascript

var Alerts = new[] {
      new Alerts { Id = 1,  Module = " Form I", Application = "Registration", Message ="1" },
      new Alerts { Id = 2,  Module = " Form I", Application = "Registration", Message ="1" },
      new Alerts { Id = 3,  Module = " Form I", Application = "Retire", Message ="1" },
      new Alerts { Id = 4,  Module = " Form I", Application = "Retire", Message ="1" },
      new Alerts { Id = 5,  Module = "Form II", Application = "Budget", Message ="1" },
      new Alerts { Id = 6,  Module = " Form I", Application = "Retire", Message ="1" },
      new Alerts { Id = 7,  Module = "Form II", Application = "Payroll", Message ="1" },
        };
on the basis of this, I have to create a web application with a button "Alert" with drop down menu "Module" and their respective child menu, and also to show the number of subsequent menus it has on them.

This is what I made so far and I know there are a lot of errors, and I cannot seem to know how to call or dispay the menu:

<!doctype html>
<html lang=''>
<head>
   <style>
.dropdown-submenu {
    position: relative;
}
.dropdown-submenu .dropdown-menu {
    top: 0;
    left: 100%;
    margin-top: -1px;
}
</style>

  <ul class ="dropdown-menu">

 </ul>
    </a>
   </li>
