Multi Selection option Lists in CRM 2011

Sometimes customers ask showing an option list whether it’s possible to have a multi selection list instead of an option list which will let the customer select only one option from the list. Unfortunately this is not supported with CRM 2011.

However there are ways to get this done and the following blog post state a very nice way to get this done. Please note as the author of the post says it’s unsupported.
