I need to convert Google's product taxonomy into a set of dropdown menus. See here: https://support.google.com/merchants/answer/1705911
Example The First drop down will have [Animals & Pet Supplies, Apparel & Accessories, Arts & Entertainment, etc.]
If you select Arts & Entertainment The second drop down will have ['/BLANK/', Event Tickets, Hobbies & Creative Arts, etc ] When you select Arts & Entertainment, Hobbies & Creative Arts, Arts & Crafts, Art & Craft Kits, Candle Making Kits. A field needs to be set of 505374.
There also needs to be a way to set all the dropdown fields by putting an ID into a text field.
