Data-binding options:

• allowExpand
• disabled
• expandDirection
• expanded

Example:

In this example, the ViewModel is defined specifically for use with the expander. It has disabled, allowExpand, expanded, and expandDirection properties that are bound in the View. If any of these values change, then the widgets automatically respond to them. The widgets also update the ViewModel values as they modify them. The expanded content appears to the right of the header. Click the header and the expanded content is hidden.

Create a ViewModel:

var viewModel = function () {  
    var self = this;  
    self.disabled = ko.observable(false);  
    self.allowExpand = ko.observable(true);  
      self.expanded = ko.observable(true);         
      self.expandDirection = ko.observable('bottom');
};

Create View with Bound Controls:

<div data-bind="wijexpander: { 
    disabled: disabled, 
    allowExpand: allowExpand, 
    expanded: expanded, 
    expandDirection: expandDirection }">
