Mustache iterate Object of array

I am looking for iterating list of objects of arrays

Here is my sample object

var Categories =    {
      "communication": [
        {
          "id": "communication_001",
          "category": "communication",
          "lastModified": "4 Day ago"
        },
        {
          "id": "communication_002",
          "category": "communication",
          "lastModified": "1 Day ago"
        }
      ],
      "social": [
        {
          "id": "social_001",
          "category": "social",
          "lastModified": "2 Day ago"
        }
      ],
      "storage": [
        {
          "id": "storage_001",
          "category": "storage",
          "lastModified": "3 Day ago"
        }
      ]
    }

here I am compling with mustache

var htmlTemplate= Mustache.render(template, { connectors: Categories });

so what will be my template for compiling?

Suggest me the mustache template.
