Is it supported to have details inside details?

Yes, you can have details inside details.

Suppose we have three objects - “Polls”, “Questions” and “Answers.” “Answers” is a detail of “Questions”. We will make “Questions” a detail of “Polls”.

One way to do this is to add an integer field “poll” to the “Questions” and the following code to the “Poll” client module:

function on_edit_form_created(item) {
    var q = task.questions.copy();

    item.edit_form.find('.form-footer').hide();

    q.view_options.form_header = false;

    q.on_view_form_created = function(quest) {
        quest.paginate = false;
    };

    q.on_before_append = function(quest) {
        if (!item.id.value) {
            quest.alert_error('Poll is not specified.');
            quest.abort();
        }
    };

    q.on_before_post = function(quest) {
        quest.poll.value = item.id.value;
    };

    q.set_where({poll: item.id.value});
    q.view(item.edit_form.find('.edit-detail'));
}

function on_field_changed(field, lookup_item) {
    var item = field.owner;
    item.apply();
    item.edit();
}


function on_before_delete(item) {
    var q = task.questions.copy();
    q.set_where({poll: item.id.value});
    q.open();
    while (!q.eof()) {
        q.delete();
    }
    q.apply();
}
