How to unfold all category?

-- HikaShop version -- : 2.6.0
-- Joomla version -- : 3.4.5
-- PHP version -- : 5.4.45
-- Browser(s) name and version -- : Chrome

Hi ,
I put a module which shows all lv1 categories from product category.
When I click first category , the lv2 categories of the category will show.
And then I click next category , the lv2 categories of the category will show.

But the lv2 categories of first category will be folded , I don't want to do it.

I hope all cateogries could be unfolded at first time. Just like tree line.

Please give me some advices.Thx~

Hi,

Edit your module via the Joomla modules manager. There, in the "hikashop options" tab, change the setting "Show children" to display all the sub elements and that will do what you want.
