Nested query loop with filter data from parent result.

[tnchuntic]

Asking if anyone have experience doing this scenario:

1. Nested query loop with filter taxonomy data from parent loop result.

ex. Product 1 single page have taxonomy 1 and we will use the taxonomy 1 to be a filter of the 2nd query loop. The goal of the nested query loop is to have a related products of the current product item displayed.
