As the topic says, it will be nice (Because of a long list 
) that hosts in the filter will be not shown, if the actually have no events.
(Maybe although good for upcoming own filters?
Like if I add the Filter „Citys“ and I enter some of them, it would be cool in the dropdown to show only the ones that have events)
Thank you for adding your idea to the Wishlist!
Could you please describe your use case in more detail? Why would you like to keep hosts without events in your widget?
This info would help us better understand your idea 
Because maybe later, they will have a new event. So I don‘t have to add them again and just choose it.
But in the dropdown it would be a long list, so it would be nice if only these are shown, wich actually have an event
Got you!
We’ll try to think it over in our future enhancements. All the updates will be posted here
Hey, I just wanted to know, if there is an update to this topic.
I really have an annoying long list of hosts and It really only needs to show the ones having events.
I a lot of topics a long time nothing happens. Thats really sad.
