| He want's certain fields in the submit-form deactivated (or blanked out/hidden), when the user selects some specific items accordingly, the hidden field pops up, or appears, or is made accessible.
This can either be done with some CSS-stylesheeding, where you have a hidden layer you make visible, or by having some InnerHTML you are writing the needed info to.
I'm not sure if theres even a solution which will work on all W3C browsers... |
