RailsAdmin with polymorphic associations

I am using, Rails 4.1, RailsAdmin 0.8.1 and Mongoid 5.0.1. I defined has_many / belongs_to relationship between Products and Pictures RailsAdmin generates a Product dropdown in the Picture model. I can choose Product or I can search for Product.

I implemented polymorphic association between Products, Pictures and Employees. Now when I edit Picture I have 2 dropdowns - to choose type (Product or Employee) and 2nd to choose the actual record.

The problem is RailsAdmin is trying to load the entire Employee or Product list into 2nd dropdown. I have many thousands Employees and eventually it timesout. Any ideas how to search?

The dropdown lists are populated when page is loaded. The second dropdown will have everything you send during page loading (before you have chosen 'type' in first dropdown).

What I think you want can be achieved using ajax to send a request when first dropdown is selected, retrieve the values and then populate your second dropdown list.
