Portal filter based on another Portal row selected
I have 2 portals on my Layout.
I Would like to If I select a row from portal1 the portal2 should perform a filter based on the row selected in the portal1.
I tried to use a variable and set it when I select a row from portal 1 but it doesn't work.
P.S: i don't know how to select by script the current row in a portal.
