I followed your instructions without success, it seem clear but it's not functioning.
It say: I enter at backend of joomla, I click on components>hikashop(business 2.2.2), then click on display>filter, I created a filter type "text"; I created a Hikashop filtering module to a "position-a", it assigned the module at a menu on all page to avoid problems, the search box is appearing, I enter a search but it's not showing nothing.¿what can it be?
I make a change at your instructions doing click on system>configuration>display and seem functioning however the styles are defficients, i did this but i do not understand because is functioning. I will like obtain more clarity about of my problem, other hand, is possible to write text on the search box and automatically the system go looking for categories or products (java)?
