Multi- level dropdown using BootStrap-4 navbar goes out of screen when dropsdown
i just can't get this to work.I uses BS4 for responsiveness. my navs are right aligned in the navbar. I tried so many things to position the submenu at the left of the parent menu... but then it does not display submenu. the same problem arises when Sub-submenu dropdowns
HTML code follows:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<!-- Style Sheets Attaches Here-->

Change the parent dropdowns to dropdown-menu-right and the CSS to position the submenu on the left instead of right...
.dropdown-submenu>.dropdown-menu {
top:0;left:-100%;margin-top:-6px;
}

Also make sure the HTML is properly structured (the code you posted is not).
