+ * Convert a form ID populated into a choice-based field into a list of fields that belong to that form.
+ *
+ * This was designed for a scenario where one field is configured to populate forms from the `gf_form` table and another
+ * field is configured to populate the form ID from the `gf_form_meta` table filtered by the selected in form in the first
+ * field. This snippet will then take the form ID, fetch the form, and populate its fields as choices.
