Ubercart

This would require a change in the DB and changes in places where attributes are displayed to make it usable... I'm not sure it's something I'd want to support in core, but you should be able to do it through a custom module if you've got some development skills.

This module would be handy.

*bump*

I've managed to get text areas. Here's how

open sites/all/modules/ubercart/uc_attribute/uc_attribute.module and do a search and replace, changing textfield to textarea.

This is not a good solution. The changes will be wiped if you upgrade the ubercart module. You will not be able to insert textfields.

I submitted a patch which adds textarea attribute support for Ubercart 2:

From being damaged from me repeatedly headbutting it. I'll have a go at implementing the patch.

Thank you.

patch works like a charm.
