Custom fields let you capture information specific to your business. Add them to any object—standard or custom.

## Steps

1. Go to **Settings → Data Model**
2. Select the object you want to add a field to
3. Click **+ New Field**
4. Choose a **field type** (see [Fields](/user-guide/data-model/capabilities/fields) for all types)
5. Enter the **field name** and optional description
6. Configure field-specific settings (see below)
7. Click **Save**

**Quick method:** Click the **+** at the end of column headers in any table view → **Customize fields**.

## Show the Field in Views

New fields aren't automatically visible. To display:
1. Open the object's table view
2. Click **Options → Fields**
3. Click the **eye icon** next to your field to show it
4. Drag to reorder

## Configuration Options

### For Select / Multi-Select

1. Click **+ Add option** to create choices
2. Set a **default option** if desired
3. Drag to reorder options

<Note>
**Use API names for imports.** Enable **Advanced mode** in Settings to see API names. See [Field Mapping](/user-guide/data-migration/capabilities/field-mapping).
</Note>

### For Currency Fields

Set the **default currency** (USD, EUR, etc.) for new records.

### For Phone Fields

Set the **default country code** to pre-fill for new phone numbers.

### Making a Field Unique

Toggle **Unique** to prevent duplicate values across records.

<Note>
If duplicates exist (including in deleted records), you'll get an error. Clean up duplicates first.
</Note>

### Setting Default Values

For Select fields, you can choose which option is pre-selected for new records. For Checkbox fields, set whether it's checked or unchecked by default.

## Deactivating a Field

1. Go to **Settings → Data Model**
2. Find the field
3. Click **⋮ → Deactivate**

Data is preserved. You can reactivate or permanently delete later.
