Hello,
Usually, if the implementation is difficult enough, the approach is probably not the right one.
If you need to render anything repeatedly you can take advantage of transformations (in repeaters or just in any static text using the ApplyTransformation method). I'll give you an example:
Let's say you have some landing documents with following properties:
Document 1
- Value: Google
- Zone: Left
Document 2
- Value: Google
- Zone: Right
Document 3
- Value: Bing
- Zone: Left
Document 4
- Value: Bing
- Zone: Left
Now you can place a repeater to your left zone, set its parameters to select all landing page and specify the Where condition property as below:
Value = {%referer%} AND Zone = 'Left'
Now you get all documents which belongs to the Left zone and matches a referer from the query string.
You can do the same with the right zone:
Value = {%referer%} AND Zone = 'Right'
Best regards,
Jan Hermann
