It may be a stupid question but I would like to ask...How to reset dropdown value to display "Choose..."?
I have tried value and defaultValue property but they don't work.
Hello "No such thing as a stupid question" :)
you can do something like this: survey.getQuestionByName("qName").value = null;
Here an example: https://plnkr.co/edit/Oe2LdJXl8P4TizwMxwGn?p=preview
It works :D
