In some cases, it's helpful to have a multi-column combo box. For example, instead of a single-column list with product codes, you could show the product names in another column.
When you select an item from the drop down list, only the product code is added to the worksheet cell.
The Lookup Lists
On another worksheet, there are two named ranges – ToolList (A1:A7) and ToolListFull (A1:B7).
The ToolListFull range is used as the ListFillRange for the Combo Box, and ToolList is used for the data validation list.
Combo Box Settings
To show two columns in the combo box, change its ColumnCount setting to 2.
When you double-click on a data validation cell, event code runs, that finds the list used in the data validation cell. Then, "Full" is added to that name, to find the list for the combo box.
