If a workflow requires input parameters, it opens a dialog box in which users enter the required input parameter values when it runs. You can organize the content and layout, or presentation, of this dialog box in Presentation tab in the workflow editor.

The way you organize parameters in the Presentation tab translates into the input parameters dialog box when the workflow runs.

The Presentation tab also allows you to add descriptions of the input parameters to help users when they provide input parameters. You can also set properties and constraints on parameters in the Presentation tab to limit the parameters that users provide. If the parameters the user provides do not meet the constraints you set in the Presentation tab, the workflow will not run.
