Attribute reference code display in dropdown

[djbasspower]

Hello!

 

How can I display the reference code from a attribute in a dropdown menu on product.tpl - like the photo I attached?

 

The code for the dropdown and color chooser is this:

 

{if ($group.group_type == 'select')}
<select name="{$groupName}" id="group_{$id_attribute_group|intval}" class="form-control attribute_select no-print">
{foreach from=$group.attributes key=id_attribute item=group_attribute}
<option value="{$id_attribute|intval}"{if (isset($smarty.get.$groupName) && $smarty.get.$groupName|intval == $id_attribute) || $group.default == $id_attribute} selected="selected"{/if} title="{$group_attribute|escape:'html':'UTF-8'}">{$group_attribute|escape:'html':'UTF-8'}</option>
{/foreach}
</select>
{elseif ($group.group_type == 'color')}
<ul id="color_to_pick_list" class="clearfix">
{assign var="default_colorpicker" value=""}
{foreach from=$group.attributes key=id_attribute item=group_attribute}
{assign var='img_color_exists' value=file_exists($col_img_dir|cat:$id_attribute|cat:'.jpg')}
<li{if $group.default == $id_attribute} class="selected"{/if}>
<a href="{$link->getProductLink($product)|escape:'html':'UTF-8'}" id="color_{$id_attribute|intval}" name="{if isset($colors.$id_attribute.value)}{$colors.$id_attribute.name|escape:'html':'UTF-8'}{/if}" class="color_pick{if ($group.default == $id_attribute)} selected{/if}"{if !$img_color_exists && isset($colors.$id_attribute.value) && $colors.$id_attribute.value} style="background: {$colors.$id_attribute.value|escape:'html':'UTF-8'};"{/if} title="{if isset($colors.$id_attribute.value)}{$colors.$id_attribute.name|escape:'html':'UTF-8'}{/if}">
{if $img_color_exists}
<img src="{$img_col_dir}{$id_attribute|intval}.jpg" alt="{$colors.$id_attribute.name|escape:'html':'UTF-8'}" title="{$colors.$id_attribute.name|escape:'html':'UTF-8'}" width="20" height="20" />
{/if}
</a>
</li>
{if ($group.default == $id_attribute)}
{$default_colorpicker = $id_attribute}
{/if}
{/foreach}
</ul>

 

big thanks in advance!
