Zeeshan's answer is indeed correct - you can use clearValue() but when you do so, the Select instance isn't reset to your defaultValue prop like you might be thinking it will be. clearValue() returns a general Select... label with no data in value.
You probably want to use selectOption() in your reset to explicitly tell react-select what value/label it should reset to. How I wired it up (using Next.js, styled-components and react-select):
import { useState, useRef } from 'react'
import styled from 'styled-components'
import Select from 'react-select'
// Basic button design for reset button
const UIButton = styled.button`
background-color: #fff;
border: none;
border-radius: 0;
color: inherit;
cursor: pointer;
font-weight: 700;
min-width: 250px;
padding: 17px 10px;
text-transform: uppercase;
transition: 0.2s ease-in-out;
&:hover {
background-color: lightgray;
}
`
// Using style object `react-select` library indicates as best practice
const selectStyles = {
control: (provided, state) => ({
...provided,
borderRadius: 0,
fontWeight: 700,
margin: '0 20px 10px 0',
padding: '10px',
textTransform: 'uppercase',
minWidth: '250px'
})
}
export default function Sample() {
// State for my data (assume `data` is valid)
const [ currentData, setCurrentData ] = useState(data.initial)
// Set refs for each select you have (one in this example)
const regionOption = useRef(null)
// Set region options, note how I have `data.initial` set here
// This is so that when my select resets, the data will reset as well
const regionSelectOptions = [
{ value: data.initial, label: 'Select a Region' },
{ value: data.regionOne, label: 'Region One' },
]
// Changes data by receiving event from select form
// We read the event's value and modify currentData accordingly
const handleSelectChange = (e) => {
setCurrentData(e.value)
}
// Reset, notice how you have to pass the selected Option you want to reset
// selectOption is smart enough to read the `value` key in regionSelectOptions
// All you have to do is pass in the array position that contains a value/label obj
// In my case this would return us to `Select a Region...` label with `data.initial` value
const resetData = () => {
regionOption.current.select.selectOption(regionSelectOptions[0])
setCurrentData(data.initial)
}
// notice how my `UIButton` for the reset is separate from my select menu
return(
<>
<h2>Select a region</h2>
<Select
aria-label="Region select menu"
defaultValue={ regionSelectOptions[0] }
onChange={ event => handleDataChange(event) }
options={ regionSelectOptions }
ref={ regionOption }
styles={ selectStyles }
/>
<UIButton
onClick={ resetData }
>
