I want to users to create a workflow at the item level. That is when they create an item in a list/library they should be able to define a workflow, consisting of tasks and approval process. All this must happen within the browser. And each workflow in the list could be different. Ofcourse there are predefined actors and actions in the workflow but the process can take any route before completion.
Are there any tools available for such tasks. I have gone through K2 Workflows but I doubt it will work for item level workflow building. Any suggestion.
