Hello,

I am using a calendar view and would like to use a many2many field for the color attribute:

<calendar string="Calendar" date_start="start_date" date_stop="end_date" color="class_code"> 

<field name = "name" string="Class"/>

</calendar>

Here I would like to add the color attribute for another field.

I need to show two color attributes (Filter) 

How can we do that?

Thanks in advance.
