I am looking to find a way to have one custom field with several things that can be entered at the same time. For example, if I have a tutorial, I would like to choose tutorial in the custom fields area and it give me several fields to enter such as "length of time", "difficulty", etc.
How can I accomplish that or is there an easier way. I am trying to do what tutsplus.com does on their tutorials. Here is an example: http://bit.ly/bEVmAn if you look right below the title of the post, you will see tutorial details.
