another way i am trying is
<MultiComboBox placeholder="Choose your sheet" id="sheetname"
width = "500px"
items="{
path: '/DATA/DROPDOWN/0/VALUE'
}" change="sheetselectionFinish">
<core:Item key="{VALUE}" text="{TEXT}" />
</MultiComboBox>
it gives dropdown but i am unable to get selected records from it in controller.
thanks,
Kotesh.
