Since you're just starting to discover the endless possibilities of WebsiteBaker, I suggest that you try entering
in your template source. This will call a 'droplet' that creates a.... yep you guessed it: search box.
Later in your journeys through the sources of WebsiteBaker, you'll learn how to modify this Search-function to your liking.
In the Settings part of the backend, you will find the template for the search results. That too can of course be changed into anything you can think of, just like everything in WB is.
