Hi,
In the file product / form that you can edit via the menu Display>Views, you have this code to display the options selector:
if(hikashop_acl('product/edit/options')) { ?>
<dt class="hikashop_product_options"><label for="data_product_options_text"><?php echo JText::_('OPTIONS'); ?></label></dt>
<dd class="hikashop_product_options"><?php
if(hikashop_level(1)) {
echo $this->nameboxType->display(
'data[product][options]',
@$this->product->options,
hikashopNameboxType::NAMEBOX_MULTIPLE,
'product',
array(
'delete' => true,
'sort' => true,
'default_text' => '<em>'.JText::_('HIKA_NONE').'</em>',
)
);
} else
echo hikashop_getUpgradeLink('essential');
?></dd>
<?php
}
There, after the line:
'default_text' => '<em>'.JText::_('HIKA_NONE').'</em>',
try adding the line:
'displayFormat' => '[{product_id}] {product_name} {xxx}',
where xxx is the column name of that Notitie custom field and it should appear in the opions selector.
