INITIAL ANSWER

There is an error with the Bootstrap v4.0.0-alpha.6 version with the transitioning that will be solved on the next release.

See the issue 22256, pull 21743 and v4.0.0-beta milestone links for more information.

For while, you can use workarounds like the @Nayana_Das example.

Answer 2

Collapse div using following code:

$(".header").click(function () {

    $header = $(this);
    //getting the next element
    $content = $header.next();
    //open up the content needed - toggle the slide- if visible, slide up, if not slidedown.
    $content.slideToggle(500, function () {
        //execute this after slideToggle is done
        //change text of header based on visibility of content div
        $header.text(function () {
            //change text based on condition
            return $content.is(":visible") ? "Collapse" : "Expand";
        });
    });

});
