I saw in openerp6 there was the possibility to show the entries of a One2Many field in a form (not kanban and not tree). So you can embed the objects in the current form and switch between them with the arrows. this feature exists still for example the global view e,g, the sale orders. You can use the arrows in the upper right to switch between the sale orders. If I set mode="form" for the One2Many field I'm getting an error because this mode is not available for One2Many fields.

Is there something similiar in v8?
