How to filter out sublists with null items

I have a list of sublists. Some sublists contain null items. I need to remove those sublists from the list. How to do it using nodes?

Thanks.

Hello,
You can use the next nodes:
Clean
IsNull

you can use the node “Is Null” set the input level to @1 (presumably, depending on your list structure), hook the result to “Any True” node with list level @2 and then “Filter By Bool Mask” setting the list input to @2
