What you are asking is 100% custom modification
(because you want to change how the things work/look) and unfortunately we don't provide free support or step-by-step instructions for custom coding modifications.
You may purchase premium support:

and let us take care this modification for you directly on your website though. 1-hour premium support is sufficient enough to cover the customization you ask.
