Hello,

 I need to pass custom param and get data from dpage sourced to the grid in my landing page.

I've a Data Page (Work-Casetype) > Sourced RD, getting case data for users with a dropdown property as filter parameter. Value can be changed dynamically in run time, so the data. Dropdown property is also created and sourced with Dpage. Reload once per interaction is also enabled. 

But I can't implement it in my portal (Pega Constellation). I've created view and referred it in my landing page. But how and where to keep the dropdown property which will pass the param to Dpage.

How can I achieve this?

Note: Same approach working well inside the case, As I can place the dropdown property (param) there. But I need this in Portal landing page.

Thank you.
