html – Bootstrap Nav Items right problem with Dropdown-ThrowExceptions

Exception or error:

I am using Bootstrap to create a Navbar. When I click on the dropdown the items in the dropdown are placed outside of the window. but they increase the window. I put ml-auto in to show the items on the right side.

dropdown

How to solve:

You need to add dropdown-menu-right to your dropdown-menu, example here

So this

<div class="dropdown-menu" aria-labelledby="navbarDropdown">

Would become this

<div class="dropdown-menu dropdown-menu-right" aria-labelledby="navbarDropdown">

edit

@flakerimi posted this just before me, but both are the same FYI.

###

Use dropdown-menu-right in

    <div class="dropdown-menu dropdown-menu-right" aria-labelledby="navbarDropdown">

Here is the fiddle

https://jsfiddle.net/9hL6soq2/

###

Wrap <div class="collapse navbar-collapse" id="navbarSupportedContent"> with a <div class="container"> and close it after <div class="collapse"> ends.

or

You can add dropdown-menu-right class to the div with class dropdown-menu.
