maxChoiceContentNestingLevel
Maximum nesting depth within choice options
Specifies how many levels of follow-up questions can be nested within choice options in Radio Button Group and Checkboxes questions. Use 0 to disable nesting, 1 to allow first-level choice options to contain nested content, 2 to allow first- and second-level choice options to contain nested content, and so on. Higher values enable deeper nesting levels.
