Sandeep,

Can you clarify what specific cascading are you looking for?

Thanks,

Kevin

If you are talking about cascading dynamic select, then it can be achieved using parameterized data pages.

There are some very good examples in Pega Academy's Senior System Architect course (Source you data with data pages lesson). 

hi Kevin,

i am exactly looking for cascading drop downs, ex:- related states dropdowns populating after we select country name in country dropdown 

hi satish,

Thanks for reply

yes it is cascading dynamic select, but dynamic select concept is in pega 6, so i am asking how can we achieve same approach in pega 7

Hi Sandeep,

for cascading of dropdowns , we use the same approach as suggested by Satish.

For the first dropdown (Country dropdown in your case) take Data page as source ( or can be anything as source) then for the second dropdown (State dropdown) take Data page as source which takes 'country' as parameter. if you have already list of states on the Data page they you can use Keyed Page Access option of Data Pages.

Hope I helped you, Please let me know if you need any more details on this

Hi Sandeep,

Please go through below link which points you to another Community post discussed about the same topic. That post is for 7.2 version. I hope the approach might be helpful for you.
