This can be done but it loses for the customer a navigation tool ... or are you using the Category Tabs at the top and that is sufficient?
You can make the categories sidebox "disappear" by utilizing an IF in the sidebox to control when it should and should show ...
This can be triggered by the presence of the:
$_GET['products_id']
If there isn't one in the URL, then you are not "looking" at the Product _info page ...
You could expand this further by creating a new sidebox that uses the inverse of this ...
For an idea of how a switch works peek in the:
/includes/modules/sidebox/manufacturer_info.php
/includes/templates/template_default/sidebox/tpl_manufacturer_info.php
and copy to your template and override directories:
/includes/modules/sidebox/your_template_dir/manufacturer_info.php
/includes/templates/your_template_dir/sidebox/tpl_manufacturer_info.php
You will see the IF statement that says only show when there is a products_id:
if (isset($_GET['products_id'])) {
Otherwise, the box hides or turns off ... :smile:
