Good day velraj

Please go through the document in the following link and take note of “Edit all rows” and “Edit single rows” -

Edit all rows - you can add or edit multiple rows, and when you click the Save button, all items are created or updated in a batch. Edit single rows - when you add or edit a single line, as soon as the line is applied (focus lost) the record is saved, here: List Views - https://help.k2.com/onlinehelp/k2cloud/userguide/current/default.htm#Create/Views/ListViews.htm.
