One of the requests or suggestions we received quite often was an easier way to display a search box. Previous to 3.7, the only ways to do this were to put it in your navigation block, use a search widget, or use your own custom code.
Now you just add your search block, and choose your options. You can choose to turn a button on/off for the visitor to click to search. You can choose what the search button will say. You can also change the placeholder text inside the search button. See below:
The block can be added to any layout to offer greater customization. We hope you enjoy the addition of this new block!
