How to check if dropdown is open in Select2?

Question

I'm using select2 and in my site. I need to know at some point if the dropdown is open or closed. I've studied the documentation but I don't see how this can be done. For example, something like this would be nice:

if ($('select').select2('isOpen') === true) { ... }

Any suggestions?

Answer 1

As of Select2 4.0.6, this has been updated to the following

$("#foo").select2("isOpen")

This will return true/false

Hope this helps!

Answer 2

Select2 4.0 has an isOpen method. If #mySelect is your HTML select element then:

$('#mySelect').data('select2').isOpen()

...will return true or false depending on the state of Select2.
