Single select
Overview
The single-select field is the core field type for business classification and data standardization. It is suitable for all scenarios that require mutually exclusive selections from predefined options. Combined with record type dependency relationships, it can display different option lists under different record types, enabling flexible configuration where multiple business lines share the same field.
Basic specifications
| Attribute | Description |
|---|---|
| Applicable scenario | Customer level (A/B/C), customer category, contract classification |
| Option limit | Up to 3,000 options |
Configuration highlights
- Default value: Set a specific option as the default value.
- Option management: Supports adding, editing, and sorting options. Each option has a label and a value (API name).
- Record type dependency: Single-select fields can be configured with record type dependencies to display different options under different record types.
Default values and required settings
Default value
The single-select field default value selects one of the predefined options as the default option.
[!NOTE] The default value is auto-filled when creating a new record in the front end. Users can modify it after pre-filling. After modifying a default value formula, historical data is not recalculated.The default value formula result must match the option’s value (API name), not the label. Otherwise, the field is not pre-filled on the create page.
Required configuration
- Field-level required: On the field configuration page, set “Required” to “Yes”. This applies across all scenarios (front-end entry and back-end import). Missing values prevent saving.
- Layout-level required: If the field is required only in specific business scenarios, set it as not required in the field properties. Then, in the specific page layout editor, check “Required”.
- Conditional required: If the required condition depends on the value of another field, configure validation rules.
Usage limitations
- When using single-select fields in formulas, be aware of the difference between label and value.
- If the single-select field default value calculation does not take effect, check whether the value in the formula matches the option’s API name.
FAQ
Single-select field displays “Option deleted” on the page
Possible causes:
- The browser cache has not been updated. Try clearing the cache.
- A non-existent option value was backfilled (the option used in the default value or function assignment has been deleted).
Troubleshooting: Confirm whether the option name has changed. Check the default value and function assignment logic.
