How can I apply automatic overflow-y scroll to drop down menu at the top.
Trying to get a sub-menu to automatically apply overflow-y for whenever the list of elements in it is longer than the current view. I have tried simply adding overflow-y with a max-height as style attributes, but that does not work

Update: I can get the overflow to work partially. I say partially because now if I apply a css class with max-height set to some value and overflow-y set to auto, then any item in that drop down menu that may have child elements no longer display to the right, but start displaying inline.
Update: I've come to realize the following. You can’t have a dropdown menu show outside of a box that is not overflow:visible. Overflow other than visible will contain all the overflow inside the scroll box. Any ideas anyone?
Hi,
Can you provide more info? Is it a menu in the content or in the layout(sidebar or header). Which demo are you using? Are you referring to the KTMenu examples ? If possible please provide the code or test link.
Regards.
Apologies for the late response. Referencing the code sample below, yes I am referring to the KTMenu examples. However, I think this issue has more to do with how the overflow and max-height work in general. Regardless, what I'm trying to do is if a user has multiple entries under the sub-menu item "Applications" that fill up or overflow the entire vertical length of the screen, I'd like to automatically apply a vertical scroll and cap the container to a max-height of let's say 640px. While I can get this done by applying a CSS class to this line:
/* Sample CSS code */
.menu-sub-lg-dropdown {
max-height: 640px;
overflow-y: auto;
}

<div class="menu-sub menu-sub-lg-down-accordion menu-sub-lg-dropdown menu-rounded-0 py-lg-4 w-lg-225px" >
Doing so forces the inner menu items to display inline, and not to the left or right of the screen which is the natural behavior of the drop-down menus.

Hi,
In the demo1 preview you can see a working example of a scrollable submenu where the scrollbar appears only when needed:
Regards.
Thanks for getting back. The issue is not that I can't get a scrollbar, it's having a scroll bar in the top menu while items in the list have sub-menu items, and having those sub-menu items appear on hover. That's where the issue is.
Hi,
Can you please try to assign data-kt-menu-overflow="true" to the parent item of the submenu ?
Regard.
