Given this json , what must my datasources schema look like?

[Greg]

[{"CompanyId":20,"CompanyName":"Walmart","CompanyContacts":[{"CompanyId":20,"FirstName":"Bob","LastName":"Green","Email":"[e-mail]"
,"Phone":"1234567","IsActive":false}]}]

This isn't doing it for me

schema: {
                  model: {
                      id:"CompanyId",
                      fields: {
                          CompanyContactId: { type: "number", editable: false, nullable: false },
                          FirstName: { type: "string", validation: { required: true } },
                          LastName: { type: "string", validation: { required: true } },
                          Email: { type: "string", validation: { required: true } },
                          Phone: { type: "string", validation: { required: true } },
                          IsActive: { type: "boolean" },
                      }
                  }
              }

Hi Greg,

Thank you for contacting us.

The presented data is hierarchical - currently the DataSource (respectively the Grid) supports only flat data. You can display nested field using a template, however you may experience troubles with some of the DataSource features such as grouping, sorting, etc.

If possible, please use flat data.
