Is it possible to group by array field?

[nhvu1988]

In this fiddle https://jsfiddle.net/j3dnm6q7/, I have data as

[
    { "name": "object 1", "category": ["cate 1", "cate 2"] },
    { "name": "object 2", "category": ["cate 1"] },
    { "name": "object 3", "category": ["cate 2"] }
]

In the ui-grid, it's ok for showing as the array but I can't make it group by separated category. It means when I press button "Group by category", only "Cate 1" and "Cate 2" will show and following the logic

• Cate 1: contains "object 1" and "object 2"
• Cate 2: contains "object 1" and "object 3"

Could ui-grid do that? or do I need to customize something?

Thank you
