How to sort a group of data

Hi guys,

I tried googling this but can't find a solution to what I'm looking for. Not sure if I can correctly name the sorting that I want to do. I am creating a case log, which will list down computer problems in my office over the coming months/years. Then I'd like to sort it either by category (PC/printer/server/lan etc) or by date.

Best if I attach a sample file for you guys to have a look. The fields are all over the place, sorry if it's a bit messy. Feel free to place the appropriate fields wherever you think best. I've created 4 different pc problems, so i'd like to sort them either by category or creation date.

I've created a dropdown list for the Category part, not sure if that'll help.

Any help appreciated guys. Thank you very much!
