On change event for custom select box

GoJS
1

I have created custom select box. I want to perform some action on selecting the dropdown items. Currently I found TextEdited event, which triggers when clicking Tab key after selecting the dropdown item

Could you please help me with the event which triggers on selection itself

Yes, the “TextEdited” DiagramEvent happens after the text editing has finished.

Your requirement “on selecting the dropdown items” seems ambiguous to me. But I think it is something that you need to implement in your HTML DOM for your <select> element.
