Formatting for Clarity

• Apply a fill color or border to the dropdown cell to indicate selection is needed.

2. Data Validation: As before, select List.
3. Reference Worksheet Cells:
   • Use the small grid icon to select cell range references instead of typing manually.

Dynamic Lists with Tables

Allow Custom Entries

• In Data Validation, uncheck the Show error alert after invalid data is entered option to permit entries beyond predefined list items.

Advanced Applications

• For cascading or dependent dropdown lists (where the options of a second dropdown depend on the first), consider further customization.
