The Header Search component allows you to easily add a number of search forms to Oxygen's header builder

Click the search icons to see the different option

'Below header' search comes with two reveal options, either fade or slide.

'Overlay header' means the search bar will take up all the available space in the header

'Fullscreen' does exactly what you think it does. You can press ESC to close.

'Expand' search allows for a more subtle search bar reveal (this could be placed anywhere on the site).
