I have a huge csv database that looks like this : 
It's a very simplified version but it gives a precise look of the structure. 
I need to be able to organise the results of this database in two ways : 
- display content by name 
- display content by name.

Also, I'd like to scan the database for dates and have access to them through a dropdown list. This would organise a given dates' informations by name and should look like this (grey rectangle is dropdown list):
Do you have an idea on how to do that ? CSV test file is available here : https://www.dropbox.com/s/1alwud24umbt95i/TestFile.csv?dl=0
