I’m not sure about anyone else, but I’m using the latest stable build of Chrome, and none of the other answers involving .blur()
work for me.
This question asks the inverse: Programmatically open a drop-down menu
The conclusion that seemed to be obtained is that it’s not possible due to the way the browser handles field element clicks.
A better solution would be to replace the dropdown with a pure HTML one and hide it when needed with a simple .hide()
command.
