In the Luxury Documentation, under the topic Main Header Setup, it mentions the following:

<<Ajax Search in menu: Enable or disable ajax search in menu>>

However, when I go to Appearance > Theme Options > Header I do not see an option for Ajax. Was this option removed from the Luxury theme?

Also, I noticed that the magnifying glass search box next to the cart icon, does not work. When I type in the search box, nothing appears as a result of my search. Is this a bug? How can I get it work so it can be used to search for products or keywords on the website?

Thanks
