Data-binding options:

• autoComplete
• autoFilter
• data
• disabled
• highlightMatching
• isEditable
• labelText
• selectedIndex
• selectionMode
• showTrigger
• triggerPosition

Example:

In this example, the ViewModel is defined specifically for use with the combobox. It has disabled, labelText, showTrigger, triggerPosition, autoFilter, autoComplete, highlightMatching, selectionMode, isEditable, selectedIndex, and data properties that are bound in the View. If any of these values change, then the widgets will automatically respond to them. The widgets also update the ViewModel values as they modify them.

The trigger (drop-down arrow) is located on the left of the combobox, and you can select more than one item from the drop-down list.

Create a ViewModel:

var viewModel = function () {  
   var self = this;  
   self.disabled = ko.observable(false);
   self.labelText = ko.observable(null);
   self.showTrigger = ko.observable(true);
   self.triggerPosition = ko.observable('right'); 
   self.autoFilter = ko.observable(true); 
   self.autoComplete = ko.observable(true); 
   self.highlightMatching = ko.observable(true); 
   self.selectionMode = ko.observable('single'); 
   self.isEditable = ko.observable(true); 
   self.selectedIndex = ko.observable(-1); 
   self.data = ko.observable(createList());
};

Create View with Bound Controls:

<input id="combo" data-bind="wijcombobox: { 
    disabled: disabled, 
    labelText: labelText, 
    showTrigger: showTrigger, 
    triggerPosition: triggerPosition, 
    isEditable: isEditable, 
    autoComplete: autoComplete, 
    autoFilter: autoFilter, 
    highlightMatching: highlightMatching, 
    selectedIndex: selectedIndex, 
    data: data,
    selectionMode:selectionMode}"/>
