Allow keydown events to propagate if Dropdown is closed

[dunal]

When element with data-toggle="dropdown" is focused, keydown events could not be cought on parent elements. For example, it's impossible to close containing modal by esc.
It would be better to prevent event propagation only if dropdown is open.

The modal scenario you described works fine for me: http://jsbin.com/gatuho/1/quiet

[dunal]

You are right, I have to make description more clear: I can catch an event on parent elements (like modal), but I can not do it on document. Please look at http://jsfiddle.net/t22ev68q/1/ - handler does not work if I press Esc, Up or Down keys.

Hi @dunal!

You appear to have posted a live example (http://fiddle.jshell.net/t22ev68q/show/light/), which is always a good first step. However, according to Bootlint, your example has some Bootstrap usage errors, which might potentially be causing your issue:

• line 59, column 1: E032: .modal-body must be a child of .modal-content

You'll need to fix these errors and post a revised example before we can proceed further.
Thanks!

Do you have an example that doesn't involve the third-party bootstrap-select library?

[dunal]

Yes, here http://jsfiddle.net/t22ev68q/2/ i used a snippet from bootstrap docs, just added tabindex="0" to make element focusable.

[cvrebert]

You need to use an anchor instead of a button to make it focusable in all browsers; see the docs example.

Tweaked example: http://jsfiddle.net/ku4vqp2y/7/show/

Well, the Up/Down keys in that case open the menu if it's closed, so that seems like reasonable+intentional behavior. I agree that preventing the propagation of Esc when the menu is closed is kinda weird though.
