Hi,
We don't have documentation specific on that.
But it can be done in a few simple steps:
- create a new filter of the type "text" applied on the data "product_name" via the menu Display>Filters
- create a new module instance of the type "HikaShop filter module" via the Joomla modules manager and select that filter in the settings of the module.
- Finally, enable the module in the position you want in your template, and in its "menu" setting set the id of a HikaShop products listing menu item configured to display all your products.
Then, when you use the input box of the module, the system will display the listing of your products of that menu item with the filter in the product_name based on what you entered in the input box, like a search module would.
