I see 3 types of behavior on the web for drop downs and I wanted to collect some insight.
When a user opens a drop down, I observe:
- the user can scroll and the drop down stays open (bootstrap)
- the user can not scroll, he is locked and needs to close the drop down by clicking somewhere else (safari and IE/edge)
- the user can scroll but it will close the drop down automatically
As I have to dev an interface I was asking myself which behavior I should enforce.
