Passing custom value to form after pressing the button

Hi All,

On my website, I have different buttons that would open a form to take user info and then guide them to a particular webpage or Url based on what button he pressed.
There are two things I wanted to do:

  1. Based on what button the user presses, show them the form with auto-selecting his option in the select field.
  2. Once the user submits the data, based on his selection, redirect to a thank you page with custom URL based on its slection
