[Erp5-users] Use category or create a new portal type for setting some attributes of a product ?

[Chetan Kumar]

Hi all
A product has an attribute called colour. At the start a list of colours 
is available. However, the organization can supply products in any 
colour that a customer orders.
Consider the scenario where an executive starts to prepare a sales order 
and the requested colour is not in the options.
Two solutions are possible here
1. Default portal_category colour is used and a new sub-category 
(portal_categories/color/new) is created by the user if it is not 
available. Access to portal_categories needs to made available to the 
user so that a new colour can be added before a new product is created 
in the system.
2. Colour can be a new portal type and relations fields are used 
(creating a new base_category to set the relation).
Which of the two options is recommended? Is there any other way ?
in this case variation axes are being considered for other attributes of 
the product.
TIA
