Autocompletion

I am using autocompletion and whenever the list is more than the actual space available it comes above the ref div but in windows it comes over the ref div and we cant see the text written in the ref(input) div, can you help for this

What is the “ref div”? And can you see this on codemirror.net/try or only on your local setup? If the latter, could it be that you have local styles interfering with the editor elements?
