This situation arises specifically when multiple stores are set up in OpenCart. When filtering by customer name on the admin side and only one customer is displayed in the results list, the "Login into Store" dropdown menu may be cut off (as shown in the first image below) on desktop browsers. However, a scrollbar appears allowing you to access the second store link by scrolling.
On mobile devices (as seen in the second image below), there is no scrollbar present, making it impossible to login to either store as they are not visible. Initially, I suspected a z-index issue but that does not seem to be the root of the problem. Any suggestions on how to resolve this?
