Currently, I am working on implementing a multi-level navbar in my project using Bootstrap Navbar along with additional CSS and Jquery.
If you want to review the codes, they can be found at: CodePen
$(function() {
// ------------------------------------------------------- //
// Multi Level dropdowns
// ------------------------------------------------------ //
$("ul.dropdown-menu [data-toggle='dropdown']").on("mouseover", function(event) {
event.preventDefault();
event.stopPropagation();
$(this).siblings().toggleClass("show");
});
$("ul.dropdown-menu [data-toggle='dropdown']").on("mouseleave", function(event) {
$(this).siblings().removeClass("show");
});
});.dropdown-submenu {
position: relative;
}
.dropdown-submenu>a:after {
content: "\f0da";
float: right;
border: none;
font-family: 'FontAwesome';
}
.dropdown-submenu>.dropdown-menu {
top: 0;
left: 100%;
margin-top: 0px;
margin-left: 0px;
}
.dropdown-item {
padding: .25rem 0.5rem!important;

</html>One issue that I am facing is the inability to hover over child elements like CF1, CF2, CF3, etc., in the sub-menus. When I move the mouse out of the parent element (e.g. Ceiling Fans), the sub-menu disappears.
