Help nesting products under categories in side bar

[reden]

Hello, I've been trying to nest the products below categories on the sidebar with UL tags. It appears to continue to add UL tags to each product vs having it add the UL tags before and after all the products to nest them under the cat, and it's not what I want... Here is a snapshot of how it looks like. Notice how it says BEGINEND. I'm using BEGIN as an example for UL and END as an example for /UL

I need BEGIN and END to nest for example, the two red items in the list so it would be a sub-list basically. I am terrible at php, so I tried my best.

<?php

  $content = "";
    $content .= '<ul>' . "\n";

  for ($i=0;$i<sizeof($box_categories_array);$i++) {
     
     //set selected style ($box_categories_array[$i]['current'] does not work)    
    
     $div_class='';
     if ($products_id){
     
         if (($products_id)&&($box_categories_array[$i]['products_id']==$products_id)){
             $div_class='category-subs-selected';
         }
     }else{
         if(($current_category_id!=0)&&($box_categories_array[$i]['category_id']==$current_category_id)){
             $div_class='category-subs-selected';
         }
     }              
    
    // set top style
    if ($box_categories_array[$i]['top'] == 'true'){    
        $a_class = 'category-top';
    }elseif($box_categories_array[$i]['has_sub_cat']){
        $a_class = 'category-subs';
    }else{
        $a_class='category-products';
    }
     // link to cat or prod
    if ($box_categories_array[$i]['is_product'] == true){
        $link = zen_href_link(FILENAME_PRODUCT_INFO, $box_categories_array[$i]['path']);
    }else{
        $link = zen_href_link(FILENAME_DEFAULT, $box_categories_array[$i]['path']);
    }
