Bootstrap-select doesn't seem to calculate the available space correctly in the case where overflow: hidden; is set in the container div.

There are workarounds of course, like setting data-size, but when the content height varies, it would be ideal if it could calculate available height under based on the container div which has overflow: hidden (if some option is set).
You need to set container: 'body'.

This solution is perfect, but the link seems to be wrong, following an alternative: http://silviomoreto.github.io/bootstrap-select/examples/#container
Spent wayyyy too much time figuring this out. Thanks everyone.
the links are outdated
