I have to create a question to ask respondents to select multiple choices. Within the multiple choices, I want to add sub-choices for two of the choices. For example,
- Select 1
- Select 2
- Sub-select 1
- Sub-select 2
- Sub-select 3
- Select 3
- Select 4
- Sub-select A
- Sub-select B
- Sub-select C
Is it possible to create this kind of question?
