Bootstrap 4 alpha how to add a drop-down menu to navigation? - html

This is from Bootstrap v4 Alpha blog theme. And I'm using this for a project. Then I tried to add a drop-down menu to this navigation bar as normal but the navigation bar dropdowns are not coming and not showing.
This is the drop-down, I tried to add to this navigation. But it's not working. Is this something I have to change from custom styles? Any input would be appreciated.
<li class="dropdown">
Dropdown <span class="caret"></span>
<ul class="dropdown-menu">
<li>About</li>
<li>Team</li>
<li class="dropdown-header">Nav header</li>
<li>Separated link</li>
<li>One more separated link</li>
</ul>
</li>

This is what a drop-down in Bootstrap 4 should look like (note: this is Bootstrap 4 release version; the alpha version is outdated):
<li class="nav-item dropdown">
<a class="nav-link dropdown-toggle" href="#" id="navbarDropdown" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
Dropdown
</a>
<div class="dropdown-menu" aria-labelledby="navbarDropdown">
<a class="dropdown-item" href="#">Action</a>
<a class="dropdown-item" href="#">Another action</a>
<div class="dropdown-divider"></div>
<a class="dropdown-item" href="#">Something else here</a>
</div>
</li>
The dropdown-item classes are missing in your code.
Here's a full navbar example for Bootstrap 4, including a drop-down:

There is multiple approaches to this, on the css for *{…} you can use *:not(.navbar){…
Or you can use !important at the end of background such as:
background-color:#33b5e5 !important;

Responsive nav bar for all screens

I am developing a WordPress website. I already edited the navbar and added some custom CSS. I will include my custom CSS below.
/** Header Customization start **/
#media screen and (min-width:1024px){ .header_area_container{
background:white;
}
.wgl-header-row_wrapper{
background:white;
}
.menu-item-1782{
background:#35a07b;
margin-left: 250px;
border-left: 1px solid white;
height: 500px;
}
.menu-item-1810{
background:#35a07b;
border-left: 1px solid white;
height: 500px;
}
.menu-item-1784{
background:#35a07b;
border-left: 1px solid white;
height: 500px;
}
.menu-item-1805{
background:#35a07b;
border-left: 1px solid white;
height: 500px;
}
.menu-item-1832{
background:#35a07b;
border-left: 1px solid white;
height: 500px;
}
.menu-item-1826{
background:#35a07b;
border-left: 1px solid white;
height: 500px;
}
.side_panel .side_panel_inner .side_panel-toggle{
/* color:black; */
margin-top:400px;
}
#menu-main-1{
margin-left:140px
}
}
/** Header Customization end **/
The problem with this CSS is I have to adjust the width of the header for separate screen versions manually and that's not a good industry standard. How can I make this responsive? I want to align my menu tabs automatically for all the desktop/laptop screen sizes.
#media screen and (min-width:1024px){ .header_area_container{

How do I stop my dropdown menu from jumping left to right?

I'm using bootstrap's responsive navbar, in mobile devices it displays a dropdown menu. This menu, be default, is aligned to the left. I changed this so that is displays to the right. I did achieve this. However, when I test on my iPhone (XR), the dropdown first shows on the left and quickly moves to the right, on its own. How can I stop this?
You can see a small video of what's happening here.

postion fixed navbar overlap other content

i´m trying to add more content under the navbar, but every time i try the navbar overlap the next items, I want fixed to always keep it in sight on the website.

I have used Bootstrap Navbar toggle with responsive behaviors, with the logo shown on the left and toggler on the right by adding class navbar-expand-lg to the <nav> tag. Also added class fixed-top for fixed navbar. To change the color of navbar refer color schemes.
Most importantly solution for the issue regarding the overlapping of content by the navbar, there needs to be some padding-top for body, which then works perfectly.
See this demo to ensure it is working.

Bootstrap 4 force parent container-fluid to include expanded dropdown

Is there a way to get the parent div ".primaryNav", shown in the example with a red background, to include my horizontal dropdown menu in MD to XL views like it does on mobile view?
Currently, I need to add a margin to the .mainNav class to increase the container height so that the background color and drop shadow align with the bottom of the sub nav and the content below it are pushed down. The issue is that when there isn't a sub nav, then the container is too tall and there is a gap.
The goal is to get the .primaryNav div to grow and include the sub nav automatically, pushing down the main content area

If you want your horizontal menu to be collapsed in MD to XL breakpoints as it is in mobile, you can use .navbar-expand-* class.
So, replace navbar-expand-md with navbar-expand-xl in #mainNav element.
<nav id="mainNav" class="navbar navbar-expand-xl navbar-light p-0">
Have you tried
<nav id="topNav" class="navbar navbar-expand-xs navbar-dark text-white px-0 justify-content-lg-end">
That should work too keep the burger menu, is that what you are trying to achieve? I could not find the div with a primaryNav class.
