For content areas it's possible to drop both blocks and pages. But how do I change which view is used for pagetypes when they're put inside a ContentArea rather than being viewed as a regular page?
Example: I have a "product page" which can be viewed as a standard page. However, the same product page can also be used in a list-view, where we only want to show title, thumbnail and price.
If I understoof you correctly you want to have different rendering for your "product page" depending where it is used, content are, list, etc
You can achieve this by registering different renderings based on a tag string, see http://world.episerver.com/Blogs/Johan-Bjornfot/Dates1/2012/9/EPiServer-7--Rendering-of-content/Read the comments too if you don't know where you would do the registering.
This way you can render the "product page" differently depending where it is used.
If unclear I can later post some code here too.
