Bootstrap dropdown adds horizontal scroll

Question

With bootstrap 4 and popper.js, whenever I add a dropdown to navbar-right and click on the button the dropdown then adds a horizontal scroll to the page and you will have to scroll right to see the whole dropdown.

How can I fix this to not have the horizontal scroll whenever the dropdown is displayed?

Here is an example of the code that I am using:

<!DOCTYPE html>
<html lang="en">
    <head>
        <meta charset="utf-8">
        <meta http-equiv="X-UA-Compatible" content="IE=edge">
        <meta name="viewport" content="initial-scale = 1.0,maximum-scale = 1.0" />

Change this:

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

to:

<div class="dropdown-menu dropdown-menu-end" aria-labelledby="dropdownMenuLink">

In short just add dropdown-menu-end class

I have overwritten the bootstrap defaults to set the min-width of the dropdown-menu to 0 and set white-space to normal for the dropdown-item. This makes the text wrap nicely and does not overflow the body.

.dropdown-menu{min-width:0;}
.dropdown-menu .dropdown-item{white-space:normal;}

Add the overflow: scroll-y property to your body

body {
    overflow: scroll-y;
    overflow-x: hidden;
}

this way no element will overflow body's width unless specified, but still allow vertical scrolling

By doing this it will cut the content of the dropdown thereby limiting the user experience. I have also seemed to have fixed it in a way that works for me - I will add an answer shortly that will show how I found a work around. – WitHeld Sep 24 '18 at 12:17
Yes that is not an optimal solution in this case but I assumed you knew you could just move the object to the left to fix it and as such wanted a specific solution that allowed no horizontal scrolling that is, after all, what you asked – Mannaroth Sep 24 '18 at 12:18
Yes your answer is correct from that perspective - I apologize for the ambiguous question . – WitHeld Sep 24 '18 at 12:53
