Drop Down Field to Drop Down Field

[fruityfreak]

Hi everyone!

I was just wondering if it's possible to do the following... And is it hard to implement such function into PHP codes...

Assume that I have a drop down field whereby a user can select the different brand mobile phone i.e. Nokia, Samsung...

For instance, when a user selects Nokia, another drop down field will update its values to the available Nokia models stated in the database, for example, 6300, 6500, etc will appear in the other drop down list...

Thanks for looking at my query...
