title: Does web.py support search box? Like the search bar on the top right of stack overflow?
body: <p>I'm new to web.py and front end. </p>
  
  <p>The problem is that I didn't find any search box support in web.py cookbook. I did some research and it seems that web.py form only supports Textbox, Password, Textarea, Dropdown, Radio, Checkbox, Button. </p>
  
  <p>I wonder if I can use form to add a search box like the right top of stackoverflow. </p>
  
  <p>Any help would be appreciated.</p>
