CSS Question

Starting Bootstrap Accordion with Minus on Active

I have my bootstrap accordion starting with 1 panel open. I also have added a JS that allows for a + or - to appear when the panel is collapsed or expanded. It works great on the panels that start collapsed, but is backwards for the panel that starts expanded. How can i fix it so that the first panel (active panel) starts with the - rather than the +?



$('.closeall').click(function() {
$('.panel-collapse.in')
.collapse('hide');
});
$('.openall').click(function() {
$('.panel-collapse:not(".in")')
.collapse('show');
});

function toggleIcon(e) {
$(e.target)
.prev('.panel-heading')
.find(".more-less")
.toggleClass('glyphicon-plus glyphicon-minus');
}
$('.panel-group').on('hidden.bs.collapse', toggleIcon);
$('.panel-group').on('shown.bs.collapse', toggleIcon);

.panel-group .panel {
border-radius: 0;
box-shadow: none;
border-color: #EEEEEE;
}
.panel-default > .panel-heading {
padding: 0;
border-radius: 0;
color: #212121;
background-color: #FAFAFA;
border-color: #EEEEEE;
}
.panel-title {
font-size: 14px;
}
.panel-title > a {
display: block;
padding: 15px;
text-decoration: none;
}
.more-less {
float: right;
color: #212121;
}
.panel-default > .panel-heading + .panel-collapse > .panel-body {
border-top-color: #EEEEEE;
}

Answer

Remove in from:

div id="collapseOne" class="panel-collapse collapse in"

and execute on document ready:

$('.panel-collapse:first').collapse('show');

Snippet:

function toggleIcon(e) {
  var currentPanel = $(e.target).closest('div.panel-default');
  $('div.panel-default').not(currentPanel).find('a[role="button"]').removeClass('glyphicon-minus').addClass('glyphicon-plus');
  currentPanel.find('a[role="button"]').removeClass('glyphicon-plus').addClass('glyphicon-minus');
}

$(function () {
  $('.closeall').click(function() {
    $('.panel-collapse.in')
    .collapse('hide');
  });
  $('.openall').click(function() {
    $('.panel-collapse:not(".in")')
    .collapse('show');
  });

  $('.panel-group').on('hidden.bs.collapse shown.bs.collapse', toggleIcon);
  $('.panel-collapse:first').collapse('show');
});
.panel-group .panel {
  border-radius: 0;
  box-shadow: none;
  border-color: #EEEEEE;
}
.panel-default > .panel-heading {
  padding: 0;
  border-radius: 0;
  color: #212121;
  background-color: #FAFAFA;
  border-color: #EEEEEE;
}
.panel-title {
  font-size: 14px;
}
.panel-title > a {
  display: block;
  padding: 15px;
  text-decoration: none;
}
.more-less {
  float: right;
  color: #212121;
}
.panel-default > .panel-heading + .panel-collapse > .panel-body {
  border-top-color: #EEEEEE;
}
