Overview
The Dropdown question presents the participant with a searchable dropdown list from which they select one option. The list of options is not hard-coded in the item itself; instead it is loaded dynamically from a prior answer in the same questionnaire, for example: the output of a CSV item.
Configuration Fields
| Field | Type | Default | Description |
|---|---|---|---|
Dropdown options label | string | '' | Required. The shortQuestion label of a prior item whose answer contains the list of options (e.g. a column from a CSV item). |
placeholder | string | 'Select' | The hint text shown inside the dropdown field before the participant makes a selection. |
How Options Are Populated
The dropdown reads its options from an answer already present in the session, for example one column produced by a preceding CSV item. At runtime, Drop down options label is used to find that answer by its label.
Participant Experience
- A labelled dropdown field is shown below the question text.
- Tapping the field opens a popup menu with a live search box, the participant can type to filter the list in real time.
- Selecting an item closes the popup and confirms the choice.
Answer
The response is stored as an integer containing the 1-based index of the selected option within the options list. For example, selecting the first option records 1, the second records 2, and so on.
The answer value is the position in the list, not the text of the selected option. To recover the label, match the index back to the options list (e.g. from the same CSV column).
