Cascading choices from EntityReference

[sebaschartrand]

Hi,

Is it possible to filter an EntityReference?

type Category = {
name : {
fr : string,
en : string
} ;
}

type Subcategory = {
category : EntityReference ;
name : {
fr : string,
en : string
} ;
}

const productSchema = buildSchema({
name : "Product",
properties : {
category: {
title: "Category",
dataType : "reference",
path : "categories",
validation : { required : true }
},
subcategory : {
title : "Subcategory",
dataType : "reference",
path : "subcategories"
},

When I create a product, I would like the subcategories to be filtered by the category selection beforehand.

Thanks a lot!
