In think n number of secondary pages and subpages we can have in a level.
Also, we can use a subpage in a secondary page but not viceversa.

Can you pls exp a bit how the data will be stored to db if we use sub page in secondary page?

Are you sure that we can do data manipulation by having sub page in secondary page?

Thanks,

suppose a secondary page is called every time a date changes in the field.
This secondary page contains details of product ,which is from a suppose X record .
This X record can have audit details also as a subrecord.
so here we can use subpage for audits in the secondary page.

this is just an example for understanding.
If I am wrong ,Please correct
