I want this to work just like Bootstrap 3. When I have a dropdown with scrollbar on hover popover, and I think there is a problem with Bootstrap 4. I need overflow:hidden; to make the dropdown scroll, but the popover is hidden too. I tried to use container:'body' but it didn't work.
$(document).ready(function() {
$('[data-toggle="popover"]').popover({
html: true,
container: 'body'
});
});.dropdown-menu{
height: 150px;
overflow: hidden;
overflow-y: auto

Reset to default 6There are some issues with popper.js, and how it positions dropdowns, popovers and tooltips. The solution is to set the data-boundary option on the popovers to window...
