Hello,

Is it possible to determine if the user creates their own value in the dropdown box, instead of picking from the list of options?  
I would like to trigger an event if they create their own value.

Thanks,  
Mike

You would need to place your own change script for the value prop:

```auto
def valueChanged(self, previousValue, currentValue, origin, missedEvents):
    if currentValue:
        if self.props.multiSelect and self.props.allowCustomOptions: # only takes action in specified conditions
            option_values = [option.value for option in self.props.options]
            for option in currentValue.value:
                if option not in option_values:
                    # custom option found

```
