CARDS-2483: Questionnaire designer: enable the "select" (dropdown) display mode for multiple choice questions

[marta-]

DRAFT because it's being published untested.

To test:

• setting displayMode: select on text, long, decimal and vocabulary questions from the questionnaire designer
• how the select questions that accept multiple answer values are behaving in the form edit mode
• check that answer options with both value and label are displayed and working correctly for select questions
• check that na options are behaving as expected for multi-valued select questions

No select for double, resource, or vocabulary questions?

No select for double, resource, or vocabulary questions?

We don't support answer options for double questions since we discovered issues with "matching" double values to options a while ago, so select doesn't currently apply to this data type.

Resource questions already have the select display mode.

I can add select to vocabulary questions, even though I find it as useless as the simple list display mode in this case, but it doesn't hurt so why not.

Resource questions already have the select display mode.

Right, I missed it because all other instances have more than just an empty object.
