Hi,
Try changing the code:
'brand' => array(
'class' => 'class.category',
'name' => 'category_name',
'mode' => 'list',
'params' => array(
'category_type' => 'manufacturer',
'filters' => array(
'c.category_depth > 1'
),
'key' => 'category_id',
),
'url' => 'category&task=findList&category_type=manufacturer',
'options' => array(
'tree_url' => 'category&task=getTree&category_type=manufacturer&category_id={ID}',
'tree_key' => '{ID}',
),
),
to:
'brand' => array(
'class' => 'class.category',
'name' => 'category_name',
'mode' => 'tree',
'params' => array(
'category_type' => 'manufacturer',
'filters' => array(
'c.category_depth > 1'
),
'key' => 'category_id',
),
'url' => 'category&task=getTree&category_type=manufacturer',
'options' => array(
'tree_url' => 'category&task=getTree&category_type=manufacturer&category_id={ID}',
'tree_key' => '{ID}',
),
),
in the file administrator/components/com_hikashop/types/namebox.php
That should help. Please let us know how it goes.
