I have been using the grid a lot for a project I am working on but have come across a major roadblock. When trying to arrange multiple columns in the grid it is really tricky to get the css I want inserted to make it look correct. Currently, to add more css fields you modify the json file in the grid options:

 [
  {
    "label": "Class",
    "description": "Set a css class",
    "key": "class",
    "view": "textstring"
  }
]

But because the key is what is used to populate the field you can not have multiple fields that add different classes. Is there a way around this as often the grid layouts I am making need more than one class to give them the correct design/layout. If someone can give me some advice on a work around I will really appreciate it. Cheers
