Need to display submenu and hide menu item - html

I have a requirement where I need to have a navigation bar on mobile view which displays a few links. These links are parent pages and will need to display the child pages underneath them on click. I need the parent menu to be hidden while the child sub menus are shown. On clicking a back button, need to show the parent menu links. Can anyone give me some ideas on how to implement this.
I've created the pages as a LI under a UL and added new UL under a LI to create a child page list.
<nav>
<ul>
<li>
<a>A</a>
<ul>
<li>
<a>aa</a>
<a>ab</a>
<a>ac</a>
</li>
</ul>
</li>
</ul>
</nav>
So my requirement is to show aa,ab,ac when A is clicked and hide the menu showing A and just shown aa,ab and ac. When back button is clicked, I need to show menu with A and hide menu with aa,ab and ac

how can I place my sidebar navigation links and icons in the middle of my sidebar

i am new to HTML and CSS so im still learning the ropes.
I would like to place my sidebar navigation links and icons in the centre of my navigation bar, as well as allow my navigation bar to turn into a drop-down menu once the site is opened on a smaller screened device. Also if you see any errors in my code or any way I can improve it please feel free to let me know, any advice would be very appreciated

.social-media {

I would suggest starting by removing
margin-left: 25%;
from the ".nav-links li" selector css.
I would continue by considering a fixed width for your sidebar. This will make it easier to find a solution for centering the nav-links.
I would also consider using flex https://www.w3schools.com/cssref/css3_pr_flex.asp to arrange the links.

Why is my dropdown navbar disappearing after I try to fix it?

My navbar is disappearing every time I try the position:fixed. I've gone through similar questions and I still can't figure it out. For that matter, the only position that is working is the position:static, all the other ones will mess up the dropdown bar or just won't show up. I'm basically just trying to make a sticky header.
.navbar {
overflow: hidden;
background-color: white;
padding: 20px 10px;
width:100%;
height: 74px;
}
/* Style the header links */
.navbar a {
float: left;
color: #9c9c9c;
text-align: center;
padding: 12px 20px;
text-decoration: none;
font-size: 20px;
line-height: 25px;
}
/* Style the logo link (notice that we set the same value of line-height and font-size to prevent the header to increase when the font gets bigger */
.navbar a.logo {
font-size: 25px;
font-weight: bold;
}
.dropdown:hover .dropbtn {
border-bottom: 5px solid #002873;
}
/* Float the link section to the right */
.navbar-right {
float: right;
}
.navbar-icon {
float: right;
padding: 1px;
}
/* Add media queries for responsiveness - when the screen is 500px wide or less, stack the links on top of each other */
#media screen and (max-width: 500px) {
.navbar a {
float: none;
display: block;
text-align: left;

Bootstrap provides a class for fixing your navbar at the top of your screen 'navbar-fixed-top'.
<nav class="navbar navbar-default navbar-fixed-top"><div class="container"></div></nav>
https://getbootstrap.com/docs/3.4/components/#navbar-fixed-top
Try setting the position property in the header element instead the .navbar:
header {
position: fixed;
}

How to make the dropdown menu open down instead of sideways?

Problem with launching of the dropdown menu
I tried to see if it was possible to use the position or text-align properties of CSS.
.navbar {
overflow: hidden;
background-color: #333;
position: fixed;
top: 0;
width: 100%;
}
.navbar a, .dropdown-content a{
float: right;
color: white;
padding: 14px 16px;
text-decoration: none;
font-size: 17px;
}
.navbar a:hover, .dropdown:hover .dropbtn {
background: red;
color: black;
}
.navbar a:active{
background: green;
color: black;
}
.dropdown-content {
display: none;
background-color: #333;
}
.dropdown-content a:hover {
background-color: red;
}
.dropdown:hover .dropdown-content {
display: block;
}

Dropdown menu is opening sideways, to the left of the dropdown button, in the navbar instead of downwards. How to make it go downwards?
Nest your menus and sub menus in an unordered list
<ul id='menu'>
<li><a href='#'>Menu</a>
<ul>
<li><a href='#'>Submenu1</a></li>
<li><a href='#'>Submenu2</a></li>
<li><a href='#'>Submenu3</a></li>
</ul>
</li>
Check out this JSSfiddle on how to setup the stylesheet.
You need to make the dropdown-content absolutely positioned and allow overflow on the navbar. So, your css should look something like this:
.navbar {
background-color: #333;
position: fixed;
top: 0;
width: 100%;
}
.dropdown {
position: relative;
float: right;
}
.navbar a{
color: white;
padding: 14px 16px;
text-decoration: none;
font-size: 17px;
}
.navbar > a, .dropbtn {
float: right;
}
.navbar a:hover, .dropdown:hover .dropbtn {
background: red;
color: black;
}
.navbar a:active{
background: green;
color: black;
}
.dropdown-content {
position: absolute;
top: 100%;
display: none;
background-color: #333;
}
.dropdown-content a {
display: block;
}
.dropdown-content a:hover {
background-color: red;
}
.dropdown:hover .dropdown-content {
display: block;
}
<div class = "navbar">
Page 6
Page 5
Page 4
Page 3
Page 2
<div class="dropdown">
<a class="dropbtn">Dropdown
<i class="fa fa-caret-down"></i>
</a>
<div class="dropdown-content">

Link 1
</ul>
</div>

Menu bar is not appearing in menu button in mobile layout

IssueTo make my website responsive for mobile layout, I am trying to make the navigation menu appear on clicking the menu button. However, the click is not working and navigation options are not appearing at all. Only the navigation menu icon is appearing. The options are appearing below the menu button separately. However, I want them to appear on clicking the menu icon.
