D7 Simple form with an items catalog grid table I need a form with a simple items catalog, user will enter quantities for each item and it will auto calculate sub total and total using javascript.

I am looking something like this:

Name: _

Email: _

Address: _

please select your items:

ID | Name   | Price | Quantity | Sub Total

1  | Item 1 | $10   | [_]  | 

2  | Item 2 | $10   | [_]  | 

3  | Item 3 | $10   | [_]  | 

Total               | 

[Submit]

Is there some module available to develop this kind of form, or I'll have to develop some custom module? I tried with Webform module but with no luck.

Thanks
I did it myself with the help of webform, webform_table_element module and by implementing a couple of hooks and a little jQuery snippet. A complete howto can be found here:

Thanks.
