I have the following CSS classes to remove the caret from a Bootstrap dropdown menu:
.caret-off::before {
display: none;
}
.caret-off::after {
display: none;
}
For a normal dropdown menu, adding the 'caret-off' class to a dropdown menu item works absolutely perfectly. The dropdown functions normally and the caret is not displayed.
However, when I attempt to add this class in conjunction with one of the directional dropdown variants, it does not work at all. In my case, I am trying to use it in conjunction with a dropdown-left menu. The dropdown works as it should, but my 'caret-off' class has no effect.
Why?
Example:
.caret-off::before {
display: none;
}
.caret-off::after {
display: none;
}

The dropdown-toggle class adds the caret, so you need to use a more specific CSS rule to target it than just caret-off. This following CSS rule will work:
.dropdown-toggle.caret-off::after {
display: none;
}
You can see here that the caret no longer appears on the dropdown-toggle class using this more specific CSS:
.dropdown-toggle.caret-off::after {
display: none;
}

The bootstrap (mobile) dropdown menu has the list items on the left. Is there any way to align them to the right?
Yes. text-align:right on the relevant ul. You might want to make that under a media query that would limit it to mobile if it changes things for your desktop view.
ul.navbar-nav {
text-align: right;
}

Thank you.
we need to change css
#navbarSupportedContent {
.navbar-nav {

Add dropdown-menu-right class in your dropdown-menu class. It will solve your problem.
<div class="dropdown-menu dropdown-menu-right">
I'm using BootStrap v4.3 and I have problem with dropdown menu in navigation, it hides after right side of screen:

I speak straight away that adding negative margin-left won't work because it breaks on mobile devices then.

I'm trying to make a full-width dropdown that looks like a collapse item - the full-width collapsable navigations that websites now use often. But I cannot figure out how to do it.
I've tried adding Bootstrap's collapse plugin to it, but that didn't work. Is it considered safe practice to add more than one .navbar-collapse class to a navigation bar?
Or should my approach be just editing Bootstrap's dropdown? And if so, how should I do it?
Here's an image to show you exactly what I'm trying to achieve:
And here's the outline of my code, please view snipped in full width:

Use w-100 (width:100%) on the dropdown-menu, and make sure the parent .dropdown
is position-static to allow the menu to expand to full width...

The reason justify-content: flex-end; doesn't work currently is because #navbarNav is width: 100%; which means it is taking up all of the available space in nav.navbar, leaving no room to shift the children of nav.navbar to the flex-start or flex-end. One way you can get nav.navbar to align it's flex-items to flex-end is assign width: auto; to #navbarNav, which will free up space to shift the children of nav.navbar to the flex-start or flex-end.
#navbarNav {
width: auto;
}
