How to Add a Clear Button to the MUI Select Component

The Material-UI Select component is a great user input component with a list of options. However, it is a bad experience to require a user to click into the component and press “backspace” to clear it. In this tutorial I will show how to add a clear button inside the Select.

The biggest challenge is removing the arrow icon and replacing it with a clear icon. I only want the clear icon when the Select has a value, and I still want the arrow icon when no value is selected:

The arrow icon is rendered by default in the Material-UI Select and there are no props to disable it, so I had to get clever with styling.

How to Clear the MUI Select

The easiest way to clear the MUI Select component is to use a state value and then set this value as the value prop in the Select component:

<const [score, setScore] = useState('');

<Select value={score} />

The score state value can be set to an empty string by a button inside the Select or by an external button. Here’s what the click handler looks like for either an internal or external button:

const handleClearClick = () => {

How to Add a Clear Button to the MUI Select

The Select component appears to me to render the same as a TextField (in fact, the TextField has a select prop that converts it to a Select component).

However, the props for adding a clear button are a little bit different. Instead of setting InputProps.endAdornment, we can directly set the endAdornment prop:

endAdornment={<IconButton sx={{display: score? "": "none"}} onClick={handleClearClick}><ClearIcon/></IconButton>}

Notice how I make it display or not display based on the score state prop. This allows the clear button to be visible only when there is a value to clear.

Remember, a display: none component is not rendered. It is best to not render a component when possible to keep the DOM light. I did not see any jumping or strange render effects with display: none.

I also made the IconButton on focus with the below nested selector, just like the Select outline does by default:

//Select level sx:
"&.Mui-focused .MuiIconButton-root": {color: 'primary.main'}

How to Remove the MUI Select Dropdown Arrow

I decided that I wanted the dropdown arrow to be visible only if no option is chosen.

//Select level sx:
"& .MuiSelect-iconOutlined": {display: score? 'none': ''}

This nested selector finds the .MuiSelect-iconOutlined class in the DOM, which wraps the dropdown arrow by default.

Using a state value for the Select allows us to manage all these styles that depend on whether the Select has been populated.
