Usage

import React from 'react';
import {render} from 'ink';
import SelectInput from 'ink-select-input';

const Demo = () => {
	const handleSelect = item => {
		// `item` = { label: 'First', value: 'first' }
	};

	const items = [
		{
			label: 'First',
			value: 'first'
		},
		{
			label: 'Second',
			value: 'second'
		},
		{
			label: 'Third',
			value: 'third'
		}
	];

	return <SelectInput items={items} onSelect={handleSelect} />;
};

render(<Demo />);

The user can navigate using arrow up/down keys or the j k keys, then press return to select. Alternatively, press the number key corresponding to an option to select it instantly.

Props

items

Type: array\ Default: []

Items to display in a list. Each item must be an object and have label and value props, it may also optionally have a key prop. If no key prop is provided, value will be used as the item key.

isFocused

Type: boolean\ Default: true

Listen to user's input. Useful in case there are multiple input components at the same time and input must be "routed" to a specific component.

initialIndex

Type: number\ Default: 0

Index of initially-selected item in items array.

limit

Type: number

Number of items to display.

indicatorComponent

Type: Component

Custom component to override the default indicator component.

itemComponent

Type: Component

Custom component to override the default item component.

onSelect

Type: function

Function to call when user selects an item. Item object is passed to that function as an argument.

onHighlight

Type: function

Function to call when user highlights an item. Item object is passed to that function as an argument.

direction

Type: 'row' | 'column'\ Default: 'column'

Controls the layout direction of the select input. When set to 'row', items will be displayed horizontally.

dividerComponent

Type: Component

Custom component to render between items when in 'row' direction. This is useful for adding visual separators between horizontal items.

Navigation

The component supports multiple navigation methods:

• Arrow keys (↑/↓ for vertical, ←/→ for horizontal)
• j/k keys (vertical only)
• Tab/Shift+Tab for cycling through items
• Number keys (1-9) for direct selection
• Return key to select the highlighted item

When using Tab/Shift+Tab navigation, the selection will loop from last to first item (and vice versa). This behavior is different from arrow key navigation, which stops at the boundaries.
