In this lesson, we create a Multi-Select Picklist. We will use this new field to record what deliverable(s), if any, that a project has. This Multi-Select Picklist is intended to work in conjunction with the Checkbox we created in the previous lesson. This is to demonstrate how that Checkboxes can be the Controlling field in a field dependency and a Multi-Select Picklist can be the Dependent field.
Please note that there are limitations and reporting issues with Multi-Select picklists. I generally recommend that you avoid using Multi-Select picklists. We will eventually retire this field in favor of a new child-object called Project Deliverables, much later in this section of this course.
