Let say on page load, there is a table (or probably select form) with two columns the first column is first name, the second one is last name, what ever is type on the input box will be high lightened on the table. If the user type "d", it will automatically high lightened the word that begins with letter d, and it will be followed by list of words in sorted order. And once I click submit button the high lightened word will be the value of post method variable.
I will post an image below to make it clear what I am trying to say.
