Here is my problem, I have objets like zone and I need to create a notebook where each page is a sub-zone, each sub-zone can contains like 40 objets.
(E.g. Zone A => Sub-zone 1 ==> obj01, obj02, etc... , Sub-zone 2 ==> obj05, obj06, etc..., Sub-zone 3 ==> obj11, obj12, etc...).
The relation between zone and sub-zone is a one2many. Actually I'm displaying all the sub-zone <field name=sub_zones_ids> with <tree limit="1000">, however this solution is not practicable when there are too much sub_zones. I really need to split the page over sub_zone. Any suggestion ?
