Bootstrap accordion, scroll to top of active (open) accordion on click?

You can animate the scroll by getting the top of the ‘target element’ and then calling animate on the body..

$('html, body').animate({
    scrollTop: $("#target-element").offset().top
}, 1000);

modifying it to be something like this will help you achieve what you are after

$('.panel-collapse').on('shown.bs.collapse', function (e) {
    var $panel = $(this).closest('.panel');
    $('html,body').animate({
        scrollTop: $panel.offset().top
    }, 500); 
});

Bootstrap 4 Example

Using the accordion example at: https://getbootstrap.com/docs/4.0/components/collapse/#accordion-example
I have modified the code to support cards.

$('.collapse').on('shown.bs.collapse', function(e) {
  var $card = $(this).closest('.card');
  $('html,body').animate({
    scrollTop: $card.offset().top
  }, 500);
});

I made it ‘prettier’…

Bootstrap 3

https://jsfiddle.net/erutfgvn/

$('.panel-collapse').on('show.bs.collapse', function(e) {
  var $panel = $(this).closest('.panel');
  var $open = $(this).closest('.panel-group').find('.panel-collapse.in');
  
  var additionalOffset = 0;
  if($panel.prevAll().filter($open.closest('.panel')).length !== 0)
  {
        additionalOffset =  $open.height();
  }
  $('html,body').animate({
    scrollTop: $panel.offset().top - additionalOffset
  }, 500);
});

Bootstrap 4

https://jsfiddle.net/9p7f0hut/

$('.collapse').on('show.bs.collapse', function(e) {
  var $card = $(this).closest('.card');
  var $open = $($(this).data('parent')).find('.collapse.show');
  
  var additionalOffset = 0;
  if($card.prevAll().filter($open.closest('.card')).length !== 0)
  {
        additionalOffset =  $open.height();
  }
  $('html,body').animate({
    scrollTop: $card.offset().top - additionalOffset
  }, 500);
});

Bootstrap 5

$('.collapse').on('shown.bs.collapse', function(e) {
  var $card = $(this).closest('.accordion-item');
  var $open = $($(this).data('parent')).find('.collapse.show');
  
  var additionalOffset = 0;
