Hi Winnie Lam 

In the dropdown, assign a local variable "MaxperPage", use the local variable "MaxperPage"  as the Max. Records of the aggregate with the List values , when the user changes the dropdown value refresh the aggregate then the value u selected on drop down will assign to the  MAX.records of aggregate you will get only how much records you want on that page

Thanks
