Coldfusion/javascript Show/hide

[nubianqnn]

I am stumped on a function to show/hide drop down elements based on a user's selection. If a user selects a second item from the first dropdown list, then I want to show a related dropdown with two options. If a user selects the second option from the second dropdown, then I want to show a data field. Somehow this is not working quite right. I am using Coldfusion to dynamically populate the dropdown. Any help will be appreciated.

Show what code you have so far.

You will need Ajax on the client-side to call the Coldfusion script to populate the dropdown. The second part will probably be solved by JavaScript alone.

you can either use Javascript itself to do stuff like:
document.getElementById('id').show();
document.getElementById('id').hide();

or if you are talking about chained select you need to implement it by Ajax.
However, if you're using CF8, it has built in dynamic select support for <cfselect> tag.

Hi,

You can use DIV function.

A DIV element is not a function. Is that what you meant?
