removing the how many items to display

Hi

i need remove the 'how many items to display' drop down menu on the product category page at the top above the products.

using the firebug tool you told me about i think im looking for hikashop_products_listing and remove the form adminForm_hikashop_category_information_menu_54_10 but im not 100% sure and cant find where these are.

ive tried using views and searching for product listing but nothing i change seems to work

where do i need to add this? in the products_listing file in views?

worked perfect thanks
