Hi,
You have this extension which does exactly that:
offlajn.com/universal-ajax-live-search/u...rch/flypage.tpl.html
extensions.joomla.org/extension/universal-ajax-live-search/
This extension is compatible with HikaShop.
However, it uses the search system in Joomla 2.x and 3.x. That search system was removed from Joomla 4 and so the extension was not updated to support the new search system in Joomla 4.
You also have this extension which does that:
www.joomlageek.com/product/component-geek-elasticsearch
extensions.joomla.org/extension/search-a.../geek-elasticsearch/
It is compatible with Joomla 4. It's quite complete, integrates with HikaShop too, is up to date, and quite powerful. However, it's more complex to setup and costs more.
There are probably other extensions on the JED which would allow you to do this:
extensions.joomla.org/tags/site-search/
Like for example:
extensions.joomla.org/extension/search-a...xing/eb-ajax-search/
But I've never heard about it so far. I just stumbled on it while I was writting this message. So I can't say much. It looks nice. It would require more investigation...
Finally, HikaShop comes with a search mechanism (
www.hikashop.com/support/documentation/1...-filter-listing.html
). It allows for filtering with dropdowns, radios, text search, etc. it displays the results using a Hikashop products listing, so it would look as good as your normal products listings. It also handle AJAX search (with auto refresh of the results while you type). And it has a module. However, for now, there is no preview of the results in a popup while you type in the filter module, like on your screenshot. That's something we could add in the future. However, that was not a priority as there already exist several alternatives to do just that.
