Dropdowns & Checkboxes
What This Does
Data validation dropdowns restrict input to predefined options. Checkboxes give boolean columns for task tracking.
Why It's Useful
Free-text status columns become inconsistent—"Done", "done", "COMPLETE". Dropdowns enforce clean data.
How to Do It
- Select cells → Data → Data validation
- Criteria: List of items or range reference
- Insert → Checkbox for true/false columns
- Reject invalid input or show warning
Try This Now
Add a dropdown with three status options to a column.
Mental Hook: Pick from list, not free type.
