selecting dropdown elements programatically

[PRashant]

Can we select /unselect dropdown elements programmatically (without user interaction with the control)?

I do not see any function in current API which supports this.

Hi Prashant, 

You can programmatically select/unselect the items using the value property, in which you can select the item by adding the value or if you would like to unselect the specific item, you can remove that particular item from the array and update the remaining value. 

select() { 

    this.mulObj.value = ['DK', 'DE', 'FR', 'CA']; 

} 

unSelect() { 

    this.mulObj.value = ['DK', 'DE']; 

}
