HTML Advanced Search - Header part

Question

Any idea or website to check out for search box on the header part of the website and a arrow or button to open a div to slide down to show advanced search option with some fields to search upon.

I know it's pretty simple but want to see and develop it through some examples.

Answer 1

Ignore any examples right now but you can utilize the HTML5 datalist element to suggest an array of values within a search box.
