Hi.

I have a assignment that I need some advice for.

I am suppose to present data in a table with information about a persons profile trainingrecords.

The table is suppose to look something like the example below where you can press on the year, month and week to get the sum of your trainingrecords in for example hours. The problem I have here is that it is easy to get a gridview for each category (year, month and week) and displaying sum, but when I now need a gridview (or somethin similar) that is dynamic and can both show and hide the different categories depending on what the user wants to see (he presses the plus-button and vice verca) I don't know where I am suppose to start. Any advice on where I can watch videos or any pointers where I should look in the API-library would be helpful.

Thanks in advance!

Example:

Sum year +

month + 

week +

day
