Select components are used for collecting user provided information from a list of options.

Basic select

Menus are positioned under their emitting elements, unless they are close to the bottom of the viewport.

Advanced features

The Select component is meant to be interchangeable with a native <select> element.

If you are looking for more advanced features, like combobox, multiselect, autocomplete, async or creatable support, head to the Autocomplete component. It's meant to be an improved version of the "react-select" and "downshift" packages.


The Select component is implemented as a custom <input> element of the InputBase. It extends the text field components subcomponents, either the OutlinedInput, Input, or FilledInput, depending on the variant selected. It shares the same styles and many of the same props. Refer to the respective component's API page for details.

Native select

As the user experience can be improved on mobile using the native select of the platform, we allow such pattern.

The TextField wrapper component is a complete form control including a label, input and help text. You can find an example with the select mode in this section.


Here are some examples of customizing the component. You can learn more about this in the overrides documentation page.

The first step is to style the InputBase component. Once it's styled, you can either use it directly as a text field or provide it to the select input prop to have a select field. Notice that the "standard" variant is easier to customize, since it does not wrap the contents in a fieldset/legend markup.

Multiple select

The Select component can handle multiple selections. It's enabled with the multiple prop.

Like with the single selection, you can pull out the new value by accessing in the onChange callback. It's always an array.






Controlling the open state

You can control the open state of the select with the open prop. Alternatively, it is also possible to set the initial (uncontrolled) open state of the component with the defaultOpen prop.

With a dialog

While it's discouraged by the Material Design guidelines, you can use a select inside a dialog.


Display categories with the ListSubheader component or the native <optgroup> element.


To properly label your Select input you need an extra element with an id that contains a label. That id needs to match the labelId of the Select e.g.

<InputLabel id="label">Age</InputLabel>
<Select labelId="label" id="select" value="20">
  <MenuItem value="10">Ten</MenuItem>
  <MenuItem value="20">Twenty</MenuItem>

Alternatively a TextField with an id and label creates the proper markup and ids for you:

<TextField id="select" label="Age" value="20" select>
  <MenuItem value="10">Ten</MenuItem>
  <MenuItem value="20">Twenty</MenuItem>

For a native select, you should mention a label by giving the value of the id attribute of the select element to the InputLabel's htmlFor attribute:

<InputLabel htmlFor="select">Age</InputLabel>
<NativeSelect id="select">
  <option value="10">Ten</option>
  <option value="20">Twenty</option>


Use the Base UI Select for complete ownership of the component's design, with no Material UI or Joy UI styles to override. This unstyled version of the component is the ideal choice for heavy customization with a smaller bundle size.
