Is it possible to have two or more widget choosers in the same page, like in example Drupals "Block Regions" or Joomlas "Module Positions"?
No the CMS only currently supports 1 widget area. There is a ticket to enable this sort of behavior. There is also a module called promospots in svn which is unreleased but will provide similar behavior to Drupals Block Regions module
Ok willr, thanks for info.
I sure hope this will be a reality in future releases of Silverstripe. Id like to test promospots when its released.
