Bootstrap collapse - go to top of the open item?

Question

I'm using the bootstrap collapse function, but when I open an element which has a lot of content, then open the next element, it jumps down and doesn't go to the top of the open element. I've tried using scrollto plugin as shown below but it doesn't work:

JS:

$(function(){
    $('a.accordion-toggle').click(function(){
        $.scrollTo( this, 500);                                             
    })
});

HTML:

<div class="accordion" id="accordion2">
    <div class="accordion-group heading-left-11">
        <h5 class="accordion-heading row">
            <a class="accordion-toggle span11" data-toggle="collapse" data-parent="#accordion2" href="#collapse1">Austria</a>
            <div class="icon-rt span1">

Any ideas?

Answer 1

Here is a solution built on others suggestions which:

• also works for embedded accordians
• scrolls so the header is also shown
• only if not already on screen
• animates as well

Code:

$('#accordion').on('shown.bs.collapse', function (e) {

  // Validate this panel belongs to this accordian, and not an embedded one
  var actualAccordianId = $('a[href="#' + $(e.target).attr('id') + '"').data('parent');
  var targetAccordianId = '#' + $(this).attr('id');
  if (actualAccordianId !== targetAccordianId) return;

  var clickedHeader = $(this).find('.panel > .collapse.in').closest('.panel').find('.panel-heading');
  var offset = clickedHeader.offset();
  var top = $(window).scrollTop();
  if(offset) {
    var topOfHeader = offset.top;
    if(topOfHeader < top) {
      $('html,body').animate({ scrollTop: topOfHeader}, 100, 'swing');
    }
  }
});

Answer 2

$('#accordion').on('shown.bs.collapse', function () {

  var panel = $(this).find('.in');

  $('html, body').animate({
        scrollTop: panel.offset().top
  }, 500);

});

Answer 3

You can try this:

I used the following, works like a charm:

$("#accordion2").bind('shown', function() {
        var active=$("#accordion_univlist .in").attr('id');
        scrollhere('#'+active);
        $('.closebutton-right').hide(); 
}); 

$('.accordion-heading').click(function () { 
  // Do something if you want to do on click  else ignore this handler.
}

function scrollhere(destination){
    var stop = $(destination).offset().top - 80;
    var delay = 1000;
    $('body,html').animate({scrollTop: stop}, delay);
    return false;
}

It also gives a bounce effect, and I like it.

Answer 4

The event name has changed in Bootstrap 3, so @bboymaanu's won't work as shown. It should use the 'shown.bs.collapse' event instead.

$(".accordion-body").on("shown.bs.collapse", function () {
    var selected = $(this);
    var collapseh = $(".collapse.in").height();
    $.scrollTo(selected, 500, {
        offset: -(collapseh)
    });
});

The new events are documented here.

Answer 5

I have scrollto working with bootstrap collapse but the code is for WordPress. I brought in your content and it works. Bootstrap Collapse has a shown event and then you need to know the height of the content to scroll up.

$(".accordion-body").on("shown", function () {
    var selected = $(this);
    var collapseh = $(".collapse .in").height();
    $.scrollTo(selected, 500, {
        offset: -(collapseh)
    });
});

You may need to tweak it a bit but it should work.

Answer 6

$(".accordion-body").on("shown", function () {
var id = $(this).attr('id');
$('html, body').animate({scrollTop: $('#'+id).offset().top + -50}, 1000);
});
});

Simple Example. The ".top + -50" is Minus 50px from the top of the element allowing some padding at the top.
