Loops and Multiple Terms in menu

Hello, I have a question.

First off let me explain what im trying to do here.

In WordPress i created custom posts(portfolio), with their own taxonomy and terms. I created a menu that displays items in their main categories and in subcategories, however this only works when these items have only 1 term selected. As soon as they have more than 1 term selected they will be displayed only under the first category (term). The menu has to show the items under every category it is included in.

In the code below i use a WP_Query to call onto all posts, and some of these posts have multiple terms.

I think part of the problem is with this: if($term_list[0] == $term->name){

It compares only the first term and therefore it will only use the first term and not any other ones, I however do not know how to solve this.

Any and all help would be greatly appriciated.
