How to display cart button in sliders with effect?

I used your instruction to organize a goods in the slider - demo.hikashop.com/index.php?option=com_c...5&Itemid=103&lang=en But how to display the cart button in this sliders? I chose the "slider_vertical" type for display of goods.

It should display if:
1. You turn on the "Display add to cart button" option of your product listing menu/module (via the menu Display>Content menus/modules.
2. There is enough pane height for the add to cart button to be displayed below the description.

Thank's it works, I had too much text in description
