When you type in part of a hostname in the search function on the top right and you get more results then can fit on the search result page you can’t select the host. Because you can’t scroll down on in this popup window.
Therefore. Can you either make the search result field with scroll function. Or Go to the “https://librenms/devices” page with the results from your search after you put in the hostname and hit enter. Or both
Hope its clear.
