I want to know which element was clicked in bootstrap menu.
I have a menu which has dropdown, so I want to know which menu item was clicked and I want to store it in browser local storage how to do this?
JS FIDDLE
I tried this for getting the menu item clicked but it does not work:
document.addEventListener('click', function(e) {
alert(e.target.id);
});

Also how to store and retrieve thier value from database?

add a delegate click event to .dropdown-menu for the anchors:-
updated fiddle
$('.dropdown-menu').on('click', 'a', function(e){
// 'this' is the clicked anchor
var text = this.text;
var href = this.href;
alert(text);
// here add to local storage;
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul class="dropdown-menu">
<li>Action</li>
<li>Another action</li>
<li>Something else here</li>
<li role="separator" class="divider"></li>
<li>Separated link</li>
</ul>

First of all, you have to be more specific about what elements you want to add a listener to. You have to add a specific class to these elements. Then you can do this easily with jQuery:
$(".yourClassName"){
//$(this) will refer to the element
}
That way you can store in local storage the content of the clicked element:
$(".yourClassName"){
var value = $(this).text();
var id = $(this).attr("id");
localStorage.setItem(id , value );
}
And that way you retrieve their value:
var value = localStorage.getItem(itemId);

Bootstrap - Why my scrollspy is not working?

I've never used scrollspy in my project and I need to know how it works. I have seen the documentation from the bootstrap page, some other stackoverflow questions and youtube videos.
I have this code:
For the nav:
<!-- Start nav -->
<nav class="navbar navbar-default navbar-fixed-top">
<div class="container-fluid">
<!-- Brand and toggle get grouped for better mobile display -->
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="#"><img id="logo" src="images/logo.png" alt="Brand"></a>
</div>
<!-- Collect the nav links, forms, and other content for toggling -->
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
<ul class="nav navbar-nav">
<li class="active">Link <span class="sr-only">(current)</span></li>
<li>Link</li>
<li class="dropdown">
Dropdown <span class="caret"></span>
<ul class="dropdown-menu">
<li>Action</li>
<li>Another action</li>
<li>Something else here</li>
<li role="separator" class="divider"></li>
<li>Separated link</li>
<li role="separator" class="divider"></li>
<li>One more separated link</li>
</ul>
</li>
</ul>
<!--<form class="navbar-form navbar-left" role="search">
<div class="form-group">
<input type="text" class="form-control" placeholder="Search">
</div>
<button type="submit" class="btn btn-default">Submit</button>
</form>-->
<ul class="nav navbar-nav navbar-right" id="navbar">
<li>Incio</li>
<li>Nuestros Servicios</li>
<li>Portafolio</li>
<!--<li class="dropdown">
Dropdown <span class="caret"></span>
<ul class="dropdown-menu">
<li>Action</li>
<li>Another action</li>
<li>Something else here</li>
<li role="separator" class="divider"></li>
<li>Separated link</li>
</ul>
</li>-->
</ul>
</div><!-- /.navbar-collapse -->
</div><!-- /.container-fluid -->
</nav>
<!-- End nav -->
For the body:
<!-- Body container -->
<div class="container-fluid">
<div class="row">
<div class="col-md-12 menu-1" id="Inicio"></div>
<div class="col-md-12 menu-2" id="NuestrosServicios"></div>
<div class="col-md-12 menu-3" id="Portafolio"></div>
</div>
</div>
<!-- End Body container -->
The JavaScript side:
$(function() {
$("body").scrollspy({target: "#navbar"});
});
The full example in jsbin:

The target should indicate to the element id. In your navbar element I don't see the id attribute. Try adding id to the navbar.
Also add the position: relative; css to your body element.
if the above didn't fix the issue use the data attribute like this data-spy="scroll" data-target="#navbar-example" in the body tag instead of javascript and don't forget the id attribute for the navbar element.

</html>

Wrap your script inside a script element and update to this, using jQuery's native fadeIn:
<script>
$('.dropdown').on('show.bs.dropdown', function () {
$(this).children('.dropdown-menu').fadeIn(500);
});
$('.dropdown').on('hide.bs.dropdown', function () {
$(this).children('.dropdown-menu').fadeOut(500);
});
</script>

Bootstrap 3 Mobile Menu with icons

UPDATE:
Thanks to brbcoding in the comments. Updated JS Fiddle
http://jsfiddle.net/Bootstrap714/RfsS9/14/
He mentioned something about transitions. How would I go about doing that or what is the best route.
Here is where I am at:
I am using Bootstrap 3 to build a menu. Bootstrap comes with a nice collapse feature for the menu when viewed on mobile. It takes the whole menu and puts it in a button to collapse. IE: if you have "link dropdown-link dropdown-link" there will be one button and it will toggle a dropdown with those links.
My question is:
Can those 3 links become each their own toggle buttons and control their own dropdowns. If you create multiple collapse toggle buttons. the toggle button opens the drop down to show the link. Then you must click on that link to open the sub-dropdown.

So basically, when in mobile, you can see the two toggle buttons. Is there a way for that toggle button to open to the sub menu instead of clicking the link and then having it open.
how it is now: toggle button, click link, then it opens
what i would like: toggle button, opens right to the drop down.

How to put animated collapse close in my menu, when click outside the button

My navbar is this:
http://jsfiddle.net/Hg4Ts/3/
my html code:
<div class="wrapper">
<div class="navbar navbar-default" role="navigation">
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="#">Project name</a>
</div>
<div class="navbar-collapse collapse">
<ul class="nav navbar-nav">
<li class="active">Link</li>
<li>Link</li>
<li>Link</li>
<li class="dropdown">
Dropdown <b class="caret"></b>
<ul class="dropdown-menu">
<li>Action</li>
<li>Another action</li>
<li>Something else here</li>
<li class="divider"></li>
<li class="dropdown-header">Nav header</li>
<li>Separated link</li>
<li>One more separated link</li>
</ul>
</li>
</ul>
<ul class="nav navbar-nav navbar-right">
<li class="active">Default</li>
<li>Static top</li>
<li>Fixed top</li>
</ul>
</div><!--/.nav-collapse -->
</div>
</div>
my javascript code:
$(document).ready(function () {
function CloseNav() {
$(".navbar-collapse").stop().css({ 'height': '1px' }).removeClass('in').addClass("collapse");
$(".navbar-toggle").stop().removeClass('collapsed');
}
$('html').click(function (event) {
var clickover = $(event.target);
var _opened = $(".navbar-collapse").hasClass("navbar-collapse in");
if (_opened === true && !clickover.hasClass("navbar-toggle")) {
CloseNav();
}
});
});
How to put animated collapse closing in my menu, when click outside the button. It´s close when click outside the button but without animation effetc. How to menu button change color only when the collapse is open?

This solution may work for you. Switch your CloseNav() function to below:
function CloseNav() {
$(".navbar-collapse").stop().animate({'height': 0},300, function () {
$('.navbar-collapse').removeClass('in').addClass("collapse");
});
$(".navbar-toggle").stop().removeClass('collapsed');
};
It looks like just adding the .collapse class to the nav bar will just switch the height immediately. If you make an animation and then add the class it creates the slide up effect you wanted.
