How do I show/hide fields in a dynamic section?

[uzegonemad]

I can't seem to figure out how to show/hide child fields inside a dynamic section.

I've tried using parent[:index].child but it causes a crash. I also tried parent.child thinking it might not require an index, but it also crashes.

My sample JSON is below. When "targeted sales funnel" is no, both the + field and all of the "year" rows should disappear. Currently, only the + field disappears.

Any insight is much appreciated!

Here's my sample JSON:

{
    "groups": [
        {
            "id": "sales-funnel",
            "title": "Targeted Sales Funnel",
            "sections": [
                {
                    "id": "is-sales-funnel",
                    "fields": [
                        {
                            "id": "is_sales_funnel",
                            "title": "This contact is in the targed sales funnel",
                            "type": "select",
                            "values": [
                                {
                                    "id": 0,
                                    "title": "No",
