Hello,
I have created a SharePoint (365) Custom List. Every list item represents a book and its metadata (the columns).
Now I would like to create a Nintex Workflow, which allows users to borrow a book.
Something like that: 
After a user pushes the button, a Nintex Workflow should be started, which writes the name of the user who triggered the Workflow into the Lent-To-Column and into the Lent-To Column till when it's lent (today's date + 30 days). Everything of course only for the Item, from which the workflow was started.
Is there any way to start a Nintex 365 Workflow from the column of a SP list item (For example the yellow button in my screenshot, but can be also a string or something else) and which also only affects changes on this item?
Or are there any best practices you would like to share with me to realize my demand?
Thanks to everyone helping me :)
