How to place the two modules the way I want? - module

Question

I've managed to create a new hook in the default template of prestashop but I can't place "featured products" under "image slider" (see image to understand what I mean).

I've added a segment of header.tpl and the place where I've put my div. Do you know what I should change in order to get the final result?
<!-- Header -->
<div id="header" class="grid_9 alpha omega">
<a id="header_logo" href="{$base_dir}" title="{$shop_name|escape:'htmlall':'UTF-8'}">
<img class="logo" src="{$logo_url}" alt="{$shop_name|escape:'htmlall':'UTF-8'}" {if $logo_image_width}width="{$logo_image_width}"{/if} {if $logo_image_height}height="{$logo_image_height}" {/if}/>
</a>
<div id="header_right" class="grid_9 omega">
{$HOOK_TOP}
</div>
</div>
<div id="columns" class="grid_9 alpha omega clearfix">
<!-- Left -->
<div id="left_column" class="column grid_2 alpha">
{$HOOK_LEFT_COLUMN}
</div>
<!-- Center -->
<div id="center_column" class=" grid_5">
<div id="myCustomHook"> {hook h='displayTop2'} </div><!--my hook-->
{/if}

Answer 1

If both "Featured Products" and "Image Slider" are attached to the same hook, you can set their positions within the hook from BackOffice > Modules > Positions.

Answer 2

You can also make this for a better control of position :
{hook h='displayTop' mod='slider'}
{hook h='displayTop' mod='homefeat'}
