Hey there, I have a sublist and this sublsit populated with saved search results. Here I am trying to edit the line in line itself, instead of clicking on edit button in the line level. How can I do that? Can anyone help me on this?

I doubt you are going to be able edit in this format. If you have a custom record with parent child relationship you can add a new record with Allow Quick Add, but editing in this format is not typically available.
