Why does the subgrid action dropdown show a scrollbar?

(1) ShareShare

Posted on by Mikko B 6
Hi,
 
I have a subgrid with two action buttons: Edit and Delete.
 
When the grid contains only one row, the action dropdown opens incorrectly - a scrollbar appears and you need to scroll down to see the buttons.
 
When the grid contains more than one row, the dropdown works as expected.
 
I've tested this in two different environments and they both work the same way.
 
Do you know what might cause this? Is there a customization or setting I should adjust?
 
Best regards,
Mikko

    Its a bug. Not sure when it started happening but it wasn't always the case.
     
    The work around is to add your own CSS something like the following, note depending on how many Actions in the menu you have you may need to change the height - think the following was for 2 actions - also may need to make it more specific if not desired to have the same setting for all grids.
     
    .view-grid {
	min-height: 13em !important;
}

    Hi 

    That behavior usually comes from how the subgrid renders the action dropdown when there’s only one row — it calculates the height as if the list might need scrolling, so a scrollbar shows up even though it’s not needed. Once you have multiple rows, the dropdown height adjusts correctly, which is why it looks fine. It’s not something caused by your customization; it’s more of a styling quirk in the default Power Pages grid component.

    You don’t really need to fix it, but if it’s bothering your users you can apply a small CSS override to remove the unnecessary scrollbar on the dropdown menu. Otherwise, this is a known UI inconsistency and not related to your data or settings.
