react-kiwi-dropdown

A minimal, easy-to-use and highly adjustable dropdown component made with ReactJS.

Why?

Styling <select> and <option> elements is a hassle when creating a custom dropdown. Many UI component libraries have great dropdown components but these are often heavily styled and not easy to overwrite. react-kiwi-dropdown is an easy to use dropdown component which makes overwriting default styles a breeze.

Usage

import React, { useState } from 'react'
import Dropdown from 'react-kiwi-dropdown'

const [selectedOption, setSelectedOption] = useState('')

const options = [
  { value: 'kiwi', content: '🥝' },
  { value: 'banana', content: '🍌' },
  { value: 'pineapple', content: '🍍' }
]

const onChange = option => {
  if (option.value === selectedOption) {
    setSelectedOption('')
  } else {
    setSelectedOption(option.value)
  }
}

return (
  <Dropdown
    options={options}
    onChange={onChange}
    buttonIndicator
    resetValue={''}
    selectedOption={selectedOption}
  />
)

Props

There's only two required props, options and onChange.

| Name | Type | Description | | ---------------------- | ------------------------- | ------------------------------------------------------------------------------------ | | options | array | An array containing option objects | | selectedOption | string / array of strings | The currently selected value/values | | resetValue | any | Used to reset select with button indicator | | onChange | function | The dropdown will call this function on change and return the selected option object | | buttonLabel | string | Button label | | buttonIndicator | boolean | Show button indicator | | buttonIndicatorContent | any | Custom content inside button indicator | | buttonArrow | 'single' or 'double' | Arrow style, single or double | | selectedOptionIcon | any | Custom icon for selected option |

Option object

| Name | Type | Description | Required | | ------- | ------ | ------------------ | -------- | | value | string | Option value | required | | content | any | Content to display | required | | icon | any | Any component |

Button indicator

The button indicator indicates if a value is selected and alo deselect all values if it's clicked while the dropdown is closed. Button indicator requires the prop resetValue. This value will be sent back when it deselects all values.

Styling

The dropdown can easily be styled by extending the component with styled-components styled() function. Use predefined classNames to add style to specific components.

| className | Description | Selected className | | ---------------------- | ------------------------ | ------------------ | | .KIWI-button | Button to toggle options | | | .KIWI-button-indicator | Button indicator | .selected | | .KIWI-option-list | Option list | | | .KIWI-option | Option | .selected |
