Adding items to menu in material design

I have this code for a menu in my html, the options I need to show in the menu are one that are input by the user, so I don't know how to add them. Should I just append everything?
<div id="demo-menu" class="mdc-menu-surface--anchor">
<button class="material-icons mdc-top-app-bar__navigation-icon mdc-icon-button" aria-label="Open navigation menu">edit</button>
<div class="mdc-menu mdc-menu-surface">
<div class="mdc-menu mdc-menu-surface">
<ul class="mdc-list" role="menu" aria-hidden="true" aria-orientation="vertical" tabindex="-1">
<li class="mdc-list-item" role="menuitem">
<span class="mdc-list-item__ripple"></span>
<span class="mdc-list-item__text">A Menu Item</span>
</li>
</ul>
</div>

Maintain scroll position when expanding <li> item

I have a bootstrap side menu that I am making. There are are <li>'s that can be expended and collapsed to display or hide additional menus/links.
Currently when i open the <li> the scroll position of the page is reset back to the top.
I would like the page to maintain its scroll position when the <li> is opened.
This is a snippet:
<div id="wrapper">
<!-- Sidebar -->
<ul class="navbar-nav bg-gradient-primary sidebar sidebar-dark accordion" id="accordionSidebar">
<!-- Sidebar - Brand -->
<a class="sidebar-brand d-flex align-items-center justify-content-center" href="/">
<div class="sidebar-brand-icon rotate-n-15">
<i class="fas fa-briefcase"></i>
</div>
<div class="sidebar-brand-text mx-3">Business Centre</div>
</a>
<!-- Nav Item - Setting Collapse Menu -->
<li class="nav-item">
<a class="nav-link collapsed" href="#" data-toggle="collapse" data-target="#collapseAccount" aria-expanded="true" aria-controls="collapseAccount">
<i class="far fa-user-circle"></i>
<span>Account</span>
</a>
<div id="collapseAccount" class="collapse" aria-labelledby="headingAccount" data-parent="#accordionSidebar">
<div class="bg-white py-2 collapse-inner rounded">
<a class="collapse-item" href="login.html">Membership</a>
<a class="collapse-item" href="login.html">Information</a>
<a class="collapse-item" href="login.html">Contact Us</a>
</div>
</div>
</li>
</ul>
</div>
Can anyone help with the code or point me in the right direction?

Its due to the # you use in href replace it with
href="JavaScript:Void(0);"
like
<a class="nav-link collapsed" href="JavaScript:Void(0);" ...
Second solution
Just use "#/" or "#!" instead of "#" and the page won't jump.

Bootstrap 3 keep menu open and show div

I've built a Nav bar with a profile dropdown (right hand side of menu):
http://www.bootply.com/Rqj51l2VFO
<nav class="navbar navbar-inverse">
<div class="container-fluid">
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#myNavbar">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
</div>
<div class="collapse navbar-collapse" id="myNavbar">
<ul class="nav navbar-nav" <!--style="width:96%" -->>
<li>Open Cases</li>
<li>Closed Cases</li>
<li><a href data-toggle="modal" data-target="#create_case" data-backdrop="true">Raise New Case</a></li>
<li class="active">{$case['object_ref']}</li>
<!-- <li style="float:right;"><span class="glyphicon glyphicon-question-sign"/></li> -->
</ul>
<!-- http://bootsnipp.com/snippets/featured/account-in-navbar -->
<ul class="nav navbar-nav navbar-right">
<li class="dropdown" id="menu">
<a href="#" data-toggle="dropdown">
<span class="glyphicon glyphicon-user"></span>
<strong>{$person['name']}</strong>
<span class="glyphicon glyphicon-chevron-down" style="margin-left: 10px;"></span>
</a>
<ul class="dropdown-menu">
<li>
<div class="navbar-login" style="width: 400px;">
<div class="row">
<div class="col-lg-4">
<p class="text-center"><span class="glyphicon glyphicon-user icon-size" style="font-size: 75px;"></span></p>
<p>Change Photo</p>
</div>
<div class="collapse" id="change_pic">
<p>Hi!</p>
</div>
<div class="col-lg-8">
<p class="text-left"><strong>Email Address</strong></p>
<p class="text-left small">{$person['main_location[email]']}</p>
</div>
</div>
</div>
</li>
<li class="divider"></li>
<li>
<div class="navbar-login navbar-login-session">
<div class="row">
<div class="col-lg-3"></div>
<div class="col-lg-6">
<p>Logout</p>
</div>
<div class="col-lg-3"></div>
</div>
</div>
</li>
</ul>
</li>
</ul>
</div>
</div>
</nav>
When I click the change photo link, I want a Div to open and the menu to stay open so the user can interact with an input that shows I.e the user would enter a URL to the photo they want in the profile.
This works fine but the menu disappears. So I added the following JS so the menu stays:
JS:
$('#menu .dropdown-menu').on({
"click": function(e) {
e.stopPropagation();
}
});
The issue I have is that now the menu stays open - the bootstrap collapse class isn't working to show/hide.
Could anybody explain what I'm doing wrong here please?

Here is one way to keep the dropdown open after click and keep collapse class working to show/hide. ...
add ID to your Change photo button:
<p>Change Photo</p>
use this following function:
$('#change-photo').on('click', function () {
$('#change_pic').toggle();
return false;
});

Render a main menu into a fixed navbar when scrolling on the browser

I'm using bootstrap latest version.
I create a main menu like this:
This is the code for in my html view:
<div class="container">
<div class="row">
<div class="btn-group btn-group-justified">
<div class="btn-group">
<button type="button" class="btn btn-nav">
<span class="glyphicon glyphicon-folder-close"></span>
<p>header Menu 1</p>
</button>
</div>
<div class="btn-group">
<button type="button" class="btn btn-nav">
<span class="glyphicon glyphicon-flash"></span>
<p>header Menu 2</p>
</button>
</div>
<div class="btn-group">
<button type="button" class="btn btn-nav">
<span class="glyphicon glyphicon-list-alt"></span>
<p>header Menu 3</p>
</button>
</div>
<div class="btn-group">
<button type="button" class="btn btn-nav">
<span class="glyphicon glyphicon-home"></span>
<p>header Menu 4</p>
</button>
</div>
<div class="btn-group">
<button type="button" class="btn btn-nav">
<span class="glyphicon glyphicon-wrench"></span>
<p>header Menu 5</p>
</button>
</div>
</div>
</div>
</div>
Now I would like, when user scrolling, change this menu into a fixed to top navbar like this (check the link to have a better idea, scroll to see the animation):
this is the code for the nav fixed to top:
<nav class="navbar navbar-default" role="navigation">
<div class="container">
<!-- Brand and toggle get grouped for better mobile display -->
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#dropdown-thumbnail-preview">
<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 active" href="#">Brand</a>
</div>
<!-- Collect the nav links, forms, and other content for toggling -->
<div class="collapse navbar-collapse" id="dropdown-thumbnail-preview">
<ul class="nav navbar-nav">

The purpose of this question is to render my main menu into a navbar fixed to top when user is scrolling.
Anybody knows what is the best solution and to make this?

You could use something like Prinzhorn/skrollr or imakewebthings/waypoints to define, when (talking about scroll position) to add/remove a class which makes the navbar sticky.

You can do something like below if you have an option of including jquery
$(window).scroll(function () {
//if you hard code, then use console
//.log to determine when you want the
//nav bar to stick.
console.log($(window).scrollTop())
if ($(window).scrollTop() > 280) //Change this value 280 as per your need
{
$('#nav_bar').addClass('navbar-fixed');
}
if ($(window).scrollTop() < 281) {
$('#nav_bar').removeClass('navbar-fixed');
}
});

Considering the structure of each navigation is different, I would suggest hiding/showing each element with a css class of hidden. Then it's just a matter of adding/removing that class when the first nav is scrolled equal to or passed the top of the viewport.
The jQuery would look something like this:
//Fired when the page is scrolling
$(window).scroll(function() {
var window = $(this);
//Create a reference to both navigations
var buttonNav = $('#buttonNav');
var fixedNav = $('#fixedNav');
if(window.scrollTop() >= buttonNav.offset().top) {
//Hide the buttonNav and Show the fixed nav
buttonNav.addClass('hidden');
fixedNav.removeClass('hidden');
} else {
//The opposite
fixedNav.addClass('hidden');
buttonNav.removeClass('hidden');
}
}
Keep in mind that you will need to add id's to each nav in order to reference them with jQuery and the hidden class just needs the css property display: none; in it. Hope this helps :)

Thanks to you all , I found a solution for my project, following the specification of my clients.
First, I add an id to the button nav, named firstMainMenu. Then, I add an id for the navbar named secondMainMenu. I add an hidden class for the navbar and make the script.
This is the script for:
$(window).scroll(function() {
if ($(this).scrollTop()>222) {
$('#secondMainMenu').removeClass('hidden').fadeIn();
$('#firstMainMenu').addClass('hidden').fadeOut('fast');
} else {
$('#secondMainMenu').fadeOut('fast');
$('#firstMainMenu').removeClass('hidden').fadeIn('slow');
}
});
This is the code who works for me. But the three answer are right too. Tahnk you to all of you for your suggestions. You are the best.
Don't hesitate if you have suggestions or edits for this script.

bootstrap menu toggle first click not working properly

Im using bootstrap-collapse.js v2.3.0, but for some reason on the first click the menu just appears and doesnt slide down.
I also noticed the height doesnt say auto , it says 205px. I dont have the menu set to this height anywhere in the CSS.
After the first click, when I go to toggle it closed, everything seems perfect, the height toggles between 0 and auto and there is a smooth transition as opposed to it instantly appearing.
Im unsure as to what code to include as it seems to be the bootstrap toggle that is the problem,
however here is the html...
I removed irrelivent bits of code..
<div class="navbar">
<div class="navbar-inner">
<a data-target=".nav-collapse" data-toggle="collapse" class="brand visible-phone">

<a data-target=".nav-collapse" data-toggle="collapse" class="btn btn-navbar">
