I am a business man and want conditional lists e.g. Categories and sub categories. For example Domestic category may have sub categories Groceries, Home Improvements etc where as Business may have Sales and Income etc.
So while one column has list of categories as items of single choice list another list depending on the the choice of categories must appear as related sub categories.
Similarly there could be a different set of people for different categories.
Please do some thing to include this.
