3. You created a dropdown menu in cell A1 with items: Red, Green, Blue. What happens if you type Yellow in A1?

medium

A. The cell clears automatically

B. The cell accepts Yellow without error

C. Yellow is automatically added to the dropdown list

D. An error message appears and prevents entry

3. Final Answer:

   An error message appears and prevents entry -> Option D

4. Quick Check:

   Invalid dropdown entry = error [OK]

Hint: Typing outside dropdown list causes error by default [OK]

Common Mistakes:

• Assuming new items auto-add to dropdown
• Thinking invalid entries are accepted silently
• Believing the cell clears automatically

2. Step 2: Fix by checking range content

   Make sure the range has visible, filled cells to appear as dropdown options.

3. Final Answer:

   Ensure the range contains visible, non-empty cells -> Option A

4. Quick Check:

   Dropdown range must have data [OK]

Hint: Check dropdown range cells are not empty [OK]

Common Mistakes:

• Changing cell format instead of range content
• Deleting dropdown unnecessarily
• Thinking browser refresh fixes data validation

5. You want a dropdown in cell B2 that shows only the names from column A where the adjacent cell in column B is not empty. How can you create this dynamic dropdown?

hard

A. Create a dropdown with all names and ignore column B

B. Manually type all names from column A into the dropdown list

C. Use Data validation with a FILTER formula like =FILTER(A:A, B:B <> "")

D. Use Data validation with a fixed range like A1:A10

Solution

1. Step 1: Understand dynamic dropdown needs

   The dropdown should show names from column A only if adjacent B cell is not empty.

2. Step 2: Use FILTER formula in Data validation

   Using =FILTER(A:A, B:B <> "") creates a dynamic list meeting the condition.

3. Step 3: Compare options

   Only Use Data validation with a FILTER formula like =FILTER(A:A, B:B <> "") uses a formula to filter dynamically; others are static or ignore the condition.

4. Final Answer:

   Use Data validation with a FILTER formula like =FILTER(A:A, B:B <> "") -> Option C

5. Quick Check:

   FILTER formula creates dynamic dropdown [OK]

Hint: Use FILTER formula in Data validation for dynamic lists [OK]

Common Mistakes:

• Typing static lists instead of dynamic formulas
• Ignoring the condition on adjacent cells
• Using fixed ranges that don't update
