What steps are needed to create a drop-down list in a cell?

To create a drop-down list in a cell, the first step involves selecting the cell where you want the drop-down list to appear. Next, you navigate to the "Data Validation" feature, which allows you to set specific parameters for the data the cell can accept. By choosing the criteria as "List," you can specify the values that will populate the drop-down options. This method is efficient because it provides users with a predefined set of choices, reducing errors in data entry and ensuring consistency in data collection.

The other choices would not successfully create a drop-down list. Entering values directly into the cell would just place those values in the cell rather than allowing selection from a list. Typing the list in a separate document and importing it is not a standard method for creating a drop-down list within a spreadsheet application; the drop-down feature is designed to work directly within the cell setup. Lastly, inserting a comment does not facilitate a drop-down list but merely adds supplementary information to the cell. Thus, the correct approach is to use the data validation feature to establish a list for user selection.
