Another Block+Subblock and 2 different arrays question

Hi guys, I guess I'm stuck. I think similar questions have been discussed before, but none of them have have exactly the points that I'm looking for.

I'm trying to merge two different arrays as block and subblock.

I have the following arrays , which are 'connected' each other by the key "catp1":

ArrayA (print_r):
Array ( [0] => Array ( [level] => 1 [catp1] => Dispositivos Móveis [num] => 19 ) [1] => Array ( [level] => 1 [catp1] => Laptops [num] => 3 ) [2] => Array ( [level] => 1 [catp1] => Tablets [num] => 1 ) )

ArrayB (print_r):
Array ( [0] => Array ( [level] => 2 [catp1] => Dispositivos Móveis [cat] => Tablets [num] => 19 ) [1] => Array ( [level] => 2 [catp1] => Laptops [cat] => Large [num] => 1 ) [2] => Array ( [level] => 2 [catp1] => Laptops [cat] => Medium [num] => 1 ) [3] => Array ( [level] => 2 [catp1] => Laptops [cat] => Small [num] => 1 ) [4] => Array ( [level] => 2 [catp1] => Tablets [cat] => Small [num] => 1 ) )

Using some stuff got from this forum:

$TBS->MergeBlock('main','array',$ArrayA);
$TBS->MergeBlock('sub','array','ArrayB[%p1%]');

And on HTML side:

<table border="1">
        <tr>
            <td>[main.catp1;block=tr;]
                <table border="1">
                    <tr>
                        <td>
                                           
                            [sub.cat;block=tr;p1=[main.catp1];]
                        </td>
                    </tr>
                </table>
            </td>
        </tr>
</table>

Unfortunately the results I have are not the ones I expected. It just outputs data from "main" and seems to completely ignore the data on the "sub" block:

Dispositivos Móveis
Laptops
Tablets

Wouldn't it output the following results?

Dispositivos Móveis
      Tablets
Laptops
       Large
       Medium
       Small
Tablets
       Small

Anyone can help me out?

Hi Antonio,

It doesn't work because [main.catp1] has values such as "Dispositivos Móveis", "Laptops", ... which are not keys of $ArrayB;

I don't think you can do the expected result with sub-template and the structure of $ArrayB : there is no sub-records under a key known by $ ArrayA.

Nevertheless, the structure of $ArrayB enables you to produce the result using a header section. See parameter "headergrp".

Thank you so much Skrol29. With your explanation everything makes sense. I'll use a header section instead of subblocks.
