React select css style

How to style react-select options in Css?

Styling a React-Select dropdown can sometimes be a challenging task for front-end developers. React-Select is a popular and highly customizable dropdown library for React applications. However, customizing the options within a React-Select dropdown can be a bit more complicated than just applying standard CSS styles. In this article, we will explore several methods to style the options within a React-Select dropdown.

Method 1: Using the styles prop

To style the options in react-select using the styles prop, you can pass an object with CSS properties to the option key. Here’s an example:

import React from 'react'; import Select from 'react-select'; const customStyles =  option: (provided, state) => ( . provided, borderBottom: '1px dotted pink', color: state.isSelected ? 'red' : 'blue', padding: 20, >), >; const options = [  value: 'chocolate', label: 'Chocolate' >,  value: 'strawberry', label: 'Strawberry' >,  value: 'vanilla', label: 'Vanilla' >, ]; function App()  return ( Select styles=customStyles> options=options> /> ); > export default App;

In this example, we define a customStyles object with a option key that returns a function. The function takes two arguments: provided and state . provided is an object that contains the default styles for the option element, and state is an object that contains information about the current state of the option (e.g. whether it is selected).

We use the spread operator ( . ) to spread the default styles from provided and then add our own custom styles. In this case, we add a pink dotted border, change the color to red if the option is selected, and set a padding of 20px.

Finally, we pass the customStyles object to the styles prop of the Select component, along with our options array.

That’s it! With just a few lines of code, we can easily style the options in react-select using the styles prop.

Method 2: Overriding default styles with CSS

To style the options of the react-select component with CSS, we can use the className prop to add a custom class to the Select component and then override the default styles with CSS. Here are the steps to do it:

Select className="custom-select" options=options> />

/* Style the options */ .custom-select__option  color: #333; background-color: #fff; padding: 8px 12px; > /* Style the selected option */ .custom-select__option--is-selected  background-color: #007bff; color: #fff; > /* Style the focused option */ .custom-select__option--is-focused  background-color: #f0f0f0; > /* Style the option when it is selected and focused */ .custom-select__option--is-selected.custom-select__option--is-focused  background-color: #007bff; color: #fff; >

In the CSS code above, we first select the custom-select__option class to style the options. We set the color and background-color properties to change the text and background colors of the options. We also set the padding property to adjust the spacing between the text and the border of the options.

Next, we select the custom-select__option—is-selected class to style the selected option. We set the background-color and color properties to change the background and text colors of the selected option.

Then, we select the custom-select__option—is-focused class to style the option when it is focused. We set the background-color property to change the background color of the focused option.

Finally, we select the custom-select__option—is-selected.custom-select__option—is-focused classes to style the option when it is both selected and focused. We set the background-color and color properties to change the background and text colors of the selected and focused option.

With these CSS styles, we can now customize the appearance of the options in the react-select component.

Method 3: Creating a custom theme with the ThemeProvider component

To style the options of react-select using a custom theme with the ThemeProvider component, you can follow these steps:

import React from 'react'; import Select,  components > from 'react-select'; import  ThemeProvider > from 'styled-components'; const customTheme = (theme) => ( . theme, colors:  . theme.colors, primary: 'red', // change the primary color neutral20: 'green', // change the option background color neutral30: 'blue', // change the option text color >, >);

const Option = (props) =>  return ( components.Option . props>> div style= color: 'white', backgroundColor: 'black' >>> /* custom option content */> props.data.label> /div> /components.Option> ); >;

1. Use the ThemeProvider component to wrap your Select component and pass the custom theme and components as props:

const App = () =>  return ( ThemeProvider theme=customTheme>> Select options=[  value: 'option1', label: 'Option 1' >,  value: 'option2', label: 'Option 2' >,  value: 'option3', label: 'Option 3' >, ]> components= Option >> /> /ThemeProvider> ); >;

This will apply the custom theme to your Select component and use the custom Option component to render the options with the specified styles. You can modify the customTheme and Option components to suit your specific styling needs.

Method 4: Extending the default styles with the makeStyles hook

To style React-Select options using the makeStyles hook, you need to follow these steps:

import  makeStyles > from '@material-ui/core/styles';

const useStyles = makeStyles( option:  // your styles here >, >);

const classes = useStyles(); Select classes= option: classes.option, >> // other props />

/* option */ .MuiList-root .MuiMenuItem-root /* option when focused */ .MuiList-root .MuiMenuItem-root.Mui-focusVisible /* option when selected */ .MuiList-root .MuiMenuItem-root.Mui-selected /* option when selected and focused */ .MuiList-root .MuiMenuItem-root.Mui-selected.Mui-focusVisible

Here’s an example styles object that changes the background color of the options when they are hovered over:

const useStyles = makeStyles( option:  '&:hover':  backgroundColor: 'lightgray', >, >, >);

And here’s an example Select component that uses the styles object:

const classes = useStyles(); Select classes= option: classes.option, >> options=options> // other props />

That’s it! With these steps, you can easily style React-Select options using the makeStyles hook.

styling react-select using classes

I am using react-select in my code. https://www.npmjs.com/package/react-select I want to style my drop down using classNames, so that I referred https://react-select.com/styles. The DOM structure of react slect is shown in the link. How can I style the react-select using classNames? Can anyone show a sample code?

If you provide the className prop to react-select, the SelectContainer will be given a className based on the provided value.

So it should work like this:

Then you can use your classname as usual.

You can also use classNamePrefix

by specifing a classNamePrefix, react-select will render all classNames with your prefix. If you use this:

Your Select will automatically render a class structure like this:

For example, given className='react-select-container' and classNamePrefix="react-select", the DOM structure is similar to this: 
 
.
 
.
 
 
 
.
 
 
 
 

.react-select-container < background-color: 'red'; >.react-select__menu

If I do my CSS as you said does it automatically the react-select or shall I specify the className in the tag? @Max

yes, give like the example says, give it: className=’react-select-container’ and classNamePrefix=»react-select»

As per the react-select official docs, there is a two ways to edit the styles by class names.

1. Static, by setting the classNamePrefix and overriding the componen class names in your own less or css file:

 className="react-select-container" classNamePrefix="react-select" /> 

2. Dynamically, by setting classnames using prop classNames:

 state.isFocused ? 'border-red-600' : 'border-grey-300', >> />
