Calendar like admin -> Customer - Date of birth in checkout attribut

Hi everybody,

I impliment an eshop with nopcommerce, which is a very good product.
But i have some cosmetic asking )

I wish implement an dynamic calendar in a checkout attributes, but for this moment it's only possible to have a Date Picker component.
Is it posssible to have an telerik.calendar in place of this ?
The same for the date of birth to customer in my accout page ?

I saw that it's possible on admin part, i think that with some coding, it'll be possible to other places :-)

Thanks for your help.

David
