Display Categories tree in module back office.

[a064855]

I am making a payment gateway and It could happen that depending on the shop manager, taxes maybe already included in the price, or not. So, when included, the tax field would be 0 and I need to get the price value without the tax. I came up with the idea of making a categories tree in the module back office where the shop manager may specify each category tax, so if it's included in the price, I can calculate it looking what category the product belongs to.

 

My problem, I do not know how to display the categories tree in the back office. How can I do it?

You can use the renderCategoryTree method of the Helper class (classes/helper/Helper.php):

 

$helper = new Helper();

$categoryTree = $helper->renderCategoryTree();

I tried this but category tree is not listed . Is there any changes needed in my configuration.tpl file
