I have a content type. Lets' call it Events. For said content type I have a field(event_type) set as an entity reference to a taxonomy named Event Type.

I've set the limit on the field(event_type) to a single value.

However, visually, I can add more than one value as a comma separated list of values.

As far as I can tell the last taxonomy term is kept as the value.

This raises the problem that at some point in time somebody may very well add more than one thinking that all of them will be kept.

Is there a way I can visually limit the values entered? Perhaps a dropdown or radio buttons or something?

If anybody can point me in the right direction I'd be grateful.

Also, I've searched in the Drupal 8 know bug list, but quite frankly the list is huge and I can't find it.

You should change the widget to a "Select list" instead of "Autocomplete (Tags style)".

You can find this on the "Manage form display" tab of the content type.
