What is the general goal of the feature?
I would like to add an additional item or choice to a list in a select widget during data collection.
For any list to select from, the feature enables updating the list during data collection to make the options on the list more and more exhaustive as data gets collected.
What are some example use cases for this feature?
I am assessing brands in the market of a specific food. A list of known brands are port of the list, but new brands my be found during data collection.
If a respondent does not find their answer as a choice in a multiple choice question (list of brand names), I would like them to be able to add their option (new brand name) as an additional item to the list so that it is part of the choices for future data entries.
Another example where this could be useful would be identifying varieties of species of birds or plants in a specific area.
