I am using the openItemCard in a custom app and I encounter 2 issues/improvements :
In the openItemCard modal, when we click on a connected board field, a pop-up appears to update this field. Unfortunately, we are unable to exit the pop-up in order to update other fields. There is no exit icon and clicking outside the pop-up does not close it
Still on the connected board field pop-up, if the screen is small, it is cut by the lower of the screen (see below screenshot). So we are unable to see the list of items or to scroll to see it.
I think this might be due to your screen size.
Decrease the zoom size in your browser by pressing the Ctrl key and scrolling down or search for how to decrease zoom size for your browser.
Hope this helps
