How to put a dropdown inside another in bootstrap 3? - html

Question

I'm designing a sidebar for mobile and trying to create a dropdown within another dropdown using bootstrap 3 but I do not get it and I do not understand what happens.
When I try to access the dropdown within another one, the two dropdown closes and I do not understand what I should do.
I think it's css problem but I do not know what happens.
//function sidebar
window.onload = function() {
window.jQuery ? $(document).ready(function() {
$(".sidebarNavigation .navbar-collapse").hide().clone().appendTo("body").removeAttr("class").addClass("sideMenu").show(), $("body").append("<div class='overlay'></div>"), $(".navbar-toggle").on("click", function() {
$(".sideMenu").addClass($(".sidebarNavigation").attr("data-sidebarClass")), $(".sideMenu, .overlay").toggleClass("open"), $(".overlay").on("click", function() {
$(this).removeClass("open"), $(".sideMenu").removeClass("open")
})
}), $(window).resize(function() {
$(".navbar-toggle").is(":hidden") ? $(".sideMenu, .overlay").hide() : $(".sideMenu, .overlay").show()
})
}) : console.log("sidebarNavigation Requires jQuery")
};
$(document).ready(function() {
// dropdown animation
$('.dropdown').on('show.bs.dropdown', function(e) {
$(this).find('.dropdown-menu').first().stop(true, true).slideDown(250);
});
$('.dropdown').on('hide.bs.dropdown', function(e) {
$(this).find('.dropdown-menu').first().stop(true, true).slideUp(0);
});
});
