Power Dropdown

Whether you are building or using complex Excel files with in-cell dropdowns for data validation, this add-in can improve your productivity by making the data validation lists friendlier to the eye and easier to use. Instead of the tiny dropdown list, you get a popup window with a filtering field. You can also add text from adjacent cells to your data validation list, like a description to help the user choose the right value, and apply static or dynamic filters to the list of entries that are displayed.

You can try the add-in for 90 days free of change; after the trial period you need to pay an annual subscription (Standard or Premium) to keep using the add-in.
