Menu
I am working on a website in which I want to create a dropdown submenu on hover in Bootstrap 4.1
The HTML code which I have used in order to create a dropdown menu on hover are:
<div class="navbar-collapse text-center" id="navbarResponsive">
<ul class="navbar-nav ml-auto">
<li class="nav-item dropdown">
<a class="nav-link dropdown-toggle" href="#" id="navbarDropdownMenuLink" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
main menu
</a>
<div class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink">
<a class="dropdown-item" href="#">A</a>
<a class="dropdown-item" href="#">B</a>
<a class="dropdown-item" href="#">C</a>
<a class="dropdown-item" href="#">D</a>
</div>
</li>
<button type="submit" onclick="location.href='/M';" class="btn btn-default">R</button>
</ul>
</div>
Problem Statement:
I am wondering what changes I should make in the code above so that on hover of D; dropdown items E, F, G, H, are shown.

Example Explained Use any element to open the dropdown menu, e.g. a <button>, <a> or <p> element. Use a container element (like <div>) to create the dropdown menu and add the dropdown links inside it. Wrap a <div> element around the button and the <div> to position the dropdown menu correctly with CSS.
Basic Dropdown To open the dropdown menu, use a button or a link with a class of . dropdown-toggle and the data-toggle="dropdown" attribute. Add the . dropdown-menu class to a <div> element to actually build the dropdown menu.
By default, a dropdown menu is automatically positioned 100% from the top and along the left side of its parent. Add . dropdown-menu-right to a . dropdown-menu to right align the dropdown menu.
No, it's not possible to have two dropdown menus inside the same div . They need to be separated since the code to toggle them looks for the first element in the parent div of the button/anchor. So if they are in the same parent div only the first will be toggled.
