Hello, 

I tried tio customize the "Client" form view adding a new sub view called "Opportunities" where i want to display the list of Opportunities related to the client.

Problem : I can't enlarge the subview to list the opportunities informations using all the space. Instead the information is on one column only (of 2). Is it possible to delete the other column and keep only one to fit all the space (large) ?

Regards
