I am using Excel 2013 and I want to have a list of items in one cell and depending on which item is selected, I want to have a second list of items shown that are dependent upon the first selection.

For example, in column A I have a data validation look up to a list of items. In column B, I want to show related items dependent upon what is selected in column A. If a user selects food, I want to have column B only show food items. However, if the user selects cars from column A, I want column B to only show car options.

I have a total of 99 various items in column A that could be selected.
