Question

Hello I want to assign multiple groups to particular customer like \"Rajat the customer\" belogs to \"Wholesale,retailer,electric\". actually I saw the same thread on Multiple c

Answer 1

I found the solution,

First of all go to database and click on the eav_attribute and then search for group_id in the attribute code field and edit this record.

now Step 1:-

change frontend_input from select to multiselect.

step 2:-

change backend_type from static to varchar.

although it is not standard way but it worked for me. :)

PS. I'm using magento 1.7.0.2 community version.
