Hi Nick , glad to hear from you ...
i have tried that but i did not get the thing work, may be i should give more detail. :)
actually i have a view data with 3 category,
so i try to use the view filter by column (some sample view filter, combine all the keys then filter) .
however i need to fixed the first category value and the 2nd & 3rd can allow user to select from a list.
eg : when user click on the menu (cat A) then i fix the (cat A) as the first category as a sessionscope.
when as the 2nd & 3rd key allow user to select is request scope.
samething happen when user click menu (cat B)then the view only show Cat B records and user can select the 2nd or 3rd key to make futher filter in the view.
if i have a page link , i will need to build every cat with one page and set the sessionscope before page load . that seem working but by this way i need to have many page , like it is not efficient .
by the way , should i use the basic node in the navigator or which way better ?
Hope to hear from you ... any suggestion are welcome ... Thank you very much.
