Drop-down lists are versatile, and ensure cleaner data compared to a free text field for when there's a limited range of possible values in a field. But that doesn't mean they won't need to change sometimes!
Note: You'll need to be an admin to change drop-down list options
Adding new options
To add new options to your list, follow these steps:
Enter customisation mode
Click on the drop-down field you'd like to add your option to
Type your new option in the 'Add drop-down options' box
Hit Enter ↵ on your keyboard
Click 'Save'
Tip: If you'd like to add options in bulk, click the button at the end of the options box. You can copy/paste from a spreadsheet or another list, and every line will be added as an option!

Click the 'X' next to any option that you no longer need
