All groups in IntegralUI Accordion directive for AngularJS, by default appear vertically and open their content downwards.

You can set accordions to appear horizontally with opening direction of left or right, and vertically with opening direction downwards or upwards.

Expand Direction

In order to change the orientation of accordion groups, we are using the expandDirection property. The following values are accepted:

  • 'down' - accordion groups are arranged vertically and open downwards
  • 'up' - accordion groups are arranged vertically and open upwards
  • 'right' - accordion groups are arranged horizontally and open on right
  • 'left' - accordion groups are arranged horizontally and open on left


.module("appModule", ["integralui"])

.controller("appCtrl", ["$scope", "IntegralUIAccordionService", "$timeout", function($scope, $ctrlService, $timeout){

// A unique identifier for the accordion

$scope.ctrlName = "ctrlSample";

// A property which determines the open direction for the accordion groups

$scope.expandMode = 'right';


// An object that holds all accordion groups

$scope.groups = [

Horizontal Accordion that Opens on Left or Right

In horizontal orientation, the opening of accordion groups is either in right or left direction. In this mode, accordion header for all groups is rotated by 90 degrees while their content panel remains the same.

Whenever accordion header is clicked or group is selected from code, it will open on left or right side, depending on whether the expandDirection is set to 'left' or 'right'.

Vertical Accordion that Opens Downwards or Upwards

By default, accordion groups are arranged in vertical layout and they open downwards. If you want accordion to appear vertically but open upwards, you can change this by setting the expandDirection property value to 'up'.


To change the opening direction in Angular Accordion directive is simple. By changing the value of expandDirection property, you can make accordion groups to open either horizontally in left or right direction or open in vertical direction downwards or upwards.
