Nested list problem: I want a Block to contain a list of properties

[MickVermeer1991]

Hi,

I have a challenge at hand: I am building a questionnaire and run into the limitation of Blockgroups not being able to contain another Blockgroup.

A questionnaire has a few properties like a title and description, furthermore an admin can add questions: you can add questions which contain a title and a type. I want the admin to be able to also create possible answers to the question, but since the amount of possible answers is variable this means I need to add a list of properties to a Block.

Any ideas of how I can add a List of answers to my question Block?

Thanks in advance!
Mick
