Newly released!! DataGrid component for REACT: http://reactdatagrid.com
The Flex CheckBoxList control is a new control provided by the Flexicious library that allows multiple select or single select checkbox list without the need for a repeater.

<!--Data bound CheckBox List example -->

<!--CheckBox List (With Flexicious)-->
<controls:CheckBoxList
dataProvider="{Employee.allStates}" rowCount="4" bindingSource="{employee1}" bindingProperty="stateCode"/>

<!--CheckBox List (Without flexicious)-->

employee.stateCode=Employee.allStates[event.target.repeaterIndex];
           
}

]]></mx:Script>

<mx:Repeater id="rptrStates" dataProvider="{Employee.allStates}">
mx:CheckBox
label="{rptrStates.currentItem.data}" data="{rptrStates.currentItem.label}" click="onStateCheckBoxChange(event )" selected="{rptrStates.currentItem.data == employee.stateCode}" />
