DropdownResponse

Defined in: parser/types.ts:610

The DropdownResponse interface is used to define the properties of a dropdown response. DropdownResponses render as a select input with user specified options.

{
  "id": "q-color",
  "prompt": "What is your favorite color?",
  "location": "aboveStimulus",
  "type": "dropdown",
  "default": "Blue",
  "placeholder": "Please choose your favorite color",
  "options": ["Red", "Blue"]
}

Here's an example of a multiselect dropdown with minimum and maximum selections:

{
  "id": "q-multiselect-dropdown",
  "prompt": "Select the fruits you like.",
  "location": "aboveStimulus",
  "type": "dropdown",
  "default": ["Banana", "Orange"],
  "placeholder": "Select your favorite fruits",
  "options": ["Apple", "Banana", "Cherry", "Grape", "Orange", "Strawberry", "Watermelon", "Pineapple"],
  "minSelections": 2,
  "maxSelections": 4
}
