With Moodle 3.3 can I add form elements to other form elements? So with reference to https://docs.moodle.org/dev/lib/formslib.php_Form_Definition#radio - could I create two radio groups and have the second 'within' the first's 'radio'? So... to have:
(o) Option one:
(o) Option one one.
(o) Option one two.
(o) Option one three [text input].
(o) Option two: [text input] [select input].
Thus only have 'Option one ...' active when 'Option one' is clicked on. And have radio elements with appended select / text inputs?
I'm an experienced Moodler but stumped on this one!
