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

selectedOptionIcon	any	Custom icon for selected option

Option object

Name	Type	Description	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
