React - Material-UI Select component with array of objects

In this short article, we would like to show how to use in React project, Material-UI Select component with array of objects as options.

By default, the select component doesn't use an options array, so it is necessary to add items inside using JSX notation.

Quick solution:

// import React, { useEffect, useState } from 'react';

// import Select from '@material-ui/core/Select/Select';
// import MenuItem from '@material-ui/core/MenuItem/MenuItem';

const options = [
    {label: 'React',      value: 'react'},
    {label: 'JavaScript', value: 'js'   },
    {label: 'TypeScript', value: 'ts'   }
];

return (
    <Select name={name} value={value}>
      {options?.map(option => {
          return (
            <MenuItem key={option.value} value={option.value}>
              {option.label ?? option.value}
            </MenuItem>
          );
      })}
    </Select>
);

 

Practical example

Presented solution uses controlled component mode (value and onChange).

ControlledSelect.jsx file:

import React, { useEffect, useState } from 'react';

import Select from '@material-ui/core/Select/Select';
import MenuItem from '@material-ui/core/MenuItem/MenuItem';

export const ControlledSelect = ({ name, value, options, onFocus, onChange, onBlur }) => {
    const [localValue, setLocalValue] = useState(value ?? '');  // we want to keep value locally
    useEffect(() => setLocalValue(value ?? ''), [value]);       // we want to update local value on prop value change
    const handleFocus = () => {
        if (onFocus) {
            onFocus();
        }
    };
    const handleChange = (e) => {
        const value = e.target.value;
        setLocalValue(value);
        if (onChange) {
            onChange(value);
        }
    };
    const handleBlur = (e) => {
        if (onBlur) {
            onBlur(e.target.value);
        }
    };
    return (
        <Select
          name={name}
          value={localValue}      // we want to work in controlled mode
          onFocus={handleFocus}
          onChange={handleChange} // we want to work in controlled mode
          onBlur={handleBlur}
        >
          {options?.map(option => {
              return (
                <MenuItem key={option.value} value={option.value}>
                  {option.label ?? option.value}
                </MenuItem>
              );
          })}
        </Select>
    );
};

export default ControlledSelect;

Example usage in App.jsx file:

import React, { useEffect, useState } from 'react';

import ControlledSelect from './ControlledSelect';

export const App = () => {
    const [value, setValue] = useState('react'); // selected option
    const options = [
        {label: 'React',      value: 'react'},
        {label: 'JavaScript', value: 'js'   },
        {label: 'TypeScript', value: 'ts'   }
    ];
    const handleChange = (value) => {
        conosle.log(`value: ${value}`);
        setValue(value);
    };
    return (
        <div>
          <label>Technology:</label>
          <ControlledSelect value={value} options={options} onChange={handleChange} />
        </div>
    );
};

export default App;
