Special Fields

Special fields provide enhanced user interface components beyond standard form controls.

Supported components include:

• Color
• Range

Color

The Color field renders a native color picker.

@KraftAdminField(
    inputType = FormInputType.COLOR
)
var themeColor: String = "#6366f1"

Administrators can choose colors visually instead of manually entering hexadecimal values.

Supported formats include:

• Hex (#6366f1)
• RGB (future)
• HSL (future)

Range

Range fields render sliders for selecting numeric values.

@KraftAdminField(
    inputType = FormInputType.RANGE
)
var completion: Int = 50

Perfect for percentages, ratings and configurable thresholds.

Validation

Range fields support standard validation.

@KraftAdminField(
    required = true,
    readonly = false
)

Future releases will introduce dedicated minimum and maximum constraints.

Typical Use Cases

Color

• Brand colors
• Theme customization
• Labels
• Categories

Range

• Volume controls
• Progress percentages
• Ratings
• Confidence scores
• Thresholds

Best Practices

Use Color whenever users need to select visual themes.

Use Range only when values exist within a bounded numeric interval and a slider provides a better experience than a number input.
