This is exactly what I like to do! I am still a bit confused on exact
implementation, however, because I have not found a way in Django to
loop through 2 structures at once in a template. The forloop.counter
seems that it is mostly used for printing the iteration through the
loop (not for indexing) and the "for loop" tag in Django is built only
to iterate through one structure at a time. Do you have any examples
how how to loop through 2 strucutres simultaneously?
Thanks!
