How to close toggle when next list is toggled

Question

This is a multi-child dropdown menu, Actually I am trying to toggle a menu one at a time (ie only selected menu will show other should close).

Here is my code

HTML

<div class="collapse navbar-collapse pull-left" id="navbar-collapse">
    <ul class="nav navbar-nav">
        <li class="nav-item dropdown">
            <a class="nav-link dropdown-toggle" href="#" data-toggle="dropdown">Master<span class="caret"></span></a>
            <ul class="dropdown-menu">
                <li class="dropdown-submenu">
                    <a class="test" tabindex="-1" href="#">MENU-A<span class="caret"></span></a>
                    <ul class="dropdown-menu">
                        <li><a tabindex="-1" href="#">A1-CHILD</a></li>
                        <li><a tabindex="-1" href="#">A2-CHILD</a></li>
                    </ul>
                </li>
                <li class="dropdown-submenu">
                    <a class="test" tabindex="-1" href="#">MENU-B<span class="caret"></span></a>
                    <ul class="dropdown-menu">
                        <li><a tabindex="-1" href="#">B1-CHILD</a></li>
                        <li><a tabindex="-1" href="#">B2CHILD</a></li>
                    </ul>
                </li>
                <li class="dropdown-submenu">
                    <a class="test" tabindex="-1" href="#">MENU-C <span class="caret"></span></a>
                    <ul class="dropdown-menu">
                        <li class="dropdown-submenu">
                            <a class="test" href="#">C1-CHILD <span class="caret"></span></a>
                            <ul class="dropdown-menu">
                                <li><a href="/supplier/create">C1-A</a></li>
                                <li><a href="/supplier/index">C1-B</a></li>
                            </ul>
                        </li>
                        <li class="dropdown-submenu">
                            <a class="test" href="#">C2-CHILD <span class="caret"></span></a>
                            <ul class="dropdown-menu">
                                <li><a href="/weight-balance-map/create">C2-A</a></li>
                                <li><a href="/weight-balance-map/create">C2-B</a></li>
                            </ul>
                        </li>
                    </ul>
                </li>
            </ul>
        </li>
    </ul>
</div>

JS :

$(document).ready(function{
  $(".dropdown-submenu a.test").on("click", function(e){
    $(this).next("ul").toggle();
    e.stopPropagation();
    e.preventDefault();
  });
});

CSS:

.dropdown-submenu {
  position: relative;
}

.dropdown-submenu .dropdown-menu {
  top: 0;
  left: 100%;
  margin-top: -1px;
}

This didn't close after another menu toggles and the third level of submenu didn't flexible for the first answer. thanks,

You need to get closest ul where click event has occur then using .not() exclude it from hiding and then simply use next("ul").toggle(); to show dropdown menu.

Demo code :

 $(document).ready(function() { $(".dropdown-submenu a.test").on("click", function(e) { //get closest `li`-> ul var selector = $(this).closest(".dropdown-submenu").find("ul"); //hid all other li and ul $(".dropdown-submenu ul").not(selector).not(this.closest('ul')).hide() $(this).next("ul").toggle(); //show this a-> next ul e.stopPropagation(); e.preventDefault(); }); });

 .dropdown-submenu { position: relative; }.dropdown-submenu.dropdown-menu { top: 0; left: 100%; margin-top: -1px; display: none; }
