Dependent Items are items that are required for another item to function properly. They’re not optional - they’re essential.
Example:
You select a shower control as your primary item. That control requires a rough-in valve to be installed behind the wall.
The valve is a dependent item - not something the client sees, but critical for the plumber.
Why this matters:
By assigning a dependent item to an Item ID, you ensure that:
It’s never forgotten
It’s clearly documented in the schedule
The installer knows what’s needed behind the scenes
