Add or remove items from a drop-down list in Excel 2013

After you create a drop-down list, you might want to add more items or delete items. How you do that depends on how the list was created. When you create a drop-down list, you connect it to a list of entries, which are used to populate your drop-down list. When you hook up those entries to your drop-down list, you can point to either a name that you’ve given the list (called a named range), or to the cells that contain your list of entries (called a range of cells).

Edit a drop-down list that’s based on a named range

1. Open the worksheet that has the named range for your drop-down list.
   Tip   To identify a named range, select the range and look for its name in the Name Box. To locate a named range, see Find named ranges.
   
   
2. Do any of the following:
   
   • To add an item, go to the end of the list and type the new item.
     
   • To remove an item, right-click its cell, click Delete, and then click OK to shift the cells up.
     
   Tip    After you edit the list, sort it the way you want it to appear in the drop-down list.
   
3. Click Formulas > Name Manager.
   
   
4. In the Name Manager box, click the named range you want to update.
   
5. To the right of the Refers to box, click the button to collapse the dialog box, and then on your worksheet select all of the cells that contain the entries for your drop-down list.
   
   
6. Click the button to expand the dialog box.
   
   
7. Click Close, and then in the box that appears, click Yes to save your changes.
