Hide/show a text box based on drop down list in php

[TechnoAtif]

HI..

I am looking for php code that will enable me to hide/show a text box based on the users previous drop down list response. If javascript comes into use for it,
its a welcome solution

(1) I want the "additional " text box to ONLY display if the user answers the drop down list with "yes"
(2) If the user answers "no" to the previous drop down list I don't want the "additional " text box displayed
(3) When the form is originally opened I dont want it to display the "additional " text box.

If you were to do javascript just use an onchange event that will call the javascript function that will be used to evaluate what the user selected. Then depending on what they select just enable or disable the text box element by it's id. When the form is originally opened just default the text box to the disabled state.
