To add a multi-choice field with options displayed in a dropdown list, choose Dropdown Menu from the Field type dropdown. New options can be added to the list by entering the value in the Add Value field and clicking the Plus icon; to remove existing options, click the Remove icon next to the value field.
The following field options are supported for dropdown menu fields:
Required field - makes data entry required before storing a sample
Note field - field information for end user displayed in a tooltip balloon
Default value - field is filled with the default value if none is provided on sample creation
After saving the field, a dropdown menu containing fixed values is created for standardised data entry. Note: dropdown menus can only accept one value at a time.
