Visual Workflow Builder (HTML5 / JQuery / CSS)

Simple workflow / flowchart editor in HTML5 / JQuery / CSS. Detailed info: - See the attached interface example. We want a webbased workflow designer. Basically you should always have a begin and end node. In between you should be able to add several types of workflow steps; - Run script - Mail user - Yes / No based decision (approve / reject) - and so on... You should be able to drag these in from the right panel where we want to list all the different types of workflow steps You should be able to move these steps around on the canvas You should be able to connect two workflow steps by dragging a line from one connection point (yellow squares) to the title of the next block When you click on the title of a step block a pop-up / overlay should appear. On this "step detail screen" you should be able to enter the details for this step. For example for the "Mail a user" step there should be the following fields there: From, To, Message You should be able to delete every workflow step but the "Begin" and "End" box. - We should be able to create workflow types ourselves based on the examples you provide. - Import: The workflow or flowchart diagram can be imported from a data file (including step details) (eg: XML or others if you have any better idea) - Export: The workflow or flowchart diagram can be exported to a data file (including step details) (eg: XML or others if you have any better idea) Important Notes: - Prefer to have developer that can prepare a demo or show related work (as I have too many programmers that committed they can do that but at the end could not deliver)
