Select
A select displays a collapsible list of options and allows a user to select one or more of them.
Installation
The above command is for individual installation only. You may skip this step if @nextui-org/react
is already installed globally.
Import
NextUI exports 3 select-related components:
- Select: The main component, which is a wrapper for the other components.
- SelectSection: The component that contains a group of select items.
- SelectItem: The component that represents a select item.
Usage
Dynamic items
Select follows the Collection Components API, accepting both static and dynamic collections.
- Static: The usage example above shows the static implementation, which can be used when the full list of options is known ahead of time.
- Dynamic: The example below can be used when the options come from an external data source such as an API call, or update over time.
Multiple Selection
You can use the selectionMode="multiple"
property to allow multiple selection.
Disabled
Disabled Items
You can disable specific items by using the disabledKeys
property.
Required
If you pass the isRequired
property to the select, it will have a danger
asterisk at
the end of the label and the select will be required.
Sizes
Colors
Variants
Radius
Label Placements
You can change the position of the label by setting the labelPlacement
property to inside
, outside
or outside-left
.
Note: If the
label
is not passed, thelabelPlacement
property will beoutside
by default.
Start Content
You can use the startContent
and endContent
properties to add content to the start and end of
the select.
Item Start & End Content
Since the Select
component uses the Listbox component under the hood, you can
use the startContent
and endContent
properties of the SelectItem
component to add content to the start
and end of the select item.
Custom Selector Icon
By default the select uses a chevron-down
icon as the selector icon which rotates when the select is open. You can
customize this icon by passing a custom one to the selectorIcon
property.
Note: Use the
disableSelectorIconRotation
property to disable the rotation of the icon.
Without Scroll Shadow
Select component uses the ScrollShadow under the hood to show a shadow when the select content is scrollable.
You can disable this shadow by passing using the scrollShadowProps
property.
Note: You can also use the
showScrollIndicators
property to disable the scroll indicators.
With Description
You can add a description to the select by passing the description
property.
With Error Message
You can combine the isInvalid
and errorMessage
properties to show an invalid select.
Controlled
You can use the selectedKeys
and onSelectionChange
/ onChange
properties to control the select value.
Using onSelectionChange
:
Using onChange
:
Controlling the open state
You can control the open state of the select by using the isOpen
and onOpenChange
/ onClose
properties.
Custom Items
You can customize the select items by modifying the SelectItem
children.
Custom Render Value
By default the select will render the selected item's text value, but you can customize this by passing a renderValue
function.
The renderValue
function receives the selected items as a parameter and must return a
ReactNode
. Check the Render Value Function section for more details.
Asynchronous Loading
Select supports asynchronous loading, in the example below we are using a custom hook to fetch the Pokemon API data in combination with the useInfiniteScroll
hook to load more data when the user reaches the end of the list.
The isLoading
prop is used to show a loading indicator instead of the selector icon when the data is being fetched.
Virtualization
Select supports virtualization, which allows efficient rendering of large lists by only rendering items that are visible in the viewport. You can enable virtualization by setting the isVirtualized
prop to true
.
Note: The virtualization strategy is based on the @tanstack/react-virtual package, which provides efficient rendering of large lists by only rendering items that are visible in the viewport.
Ten Thousand Items
Here's an example of using virtualization with 10,000 items.
Max Listbox Height
The maxListboxHeight
prop is used to set the maximum height of the listbox. This is required when using virtualization. By default, it's set to 256
.
Custom Item Height
The itemHeight
prop is used to set the height of each item in the listbox. This is required when using virtualization. By default, it's set to 32
.
With Sections
You can use the SelectSection
component to group select items.
Custom Sections Style
You can customize the sections style by using the classNames
property of the SelectSection
component.
Multiple Select Controlled
You can use the same properties as the single select to control the multiple select, selectedKeys
and onSelectionChange
/ onChange
.
Using onSelectionChange
:
Using onChange
:
Multiple With Chips
You can render any component as the select value by using the renderValue
property. In this example we are
using the Chip component to render the selected items.
Note: Make sure to pass the
isMultiline
property to theSelect
component to allow the chips to wrap.
The renderValue
function receives the selected items as a parameter and must return a
ReactNode
. Check the Render Value Function section for more details.
Customizing the select
You can customize any slot of the select by using the classNames
property. Select
component also provides the popoverProps and listboxProps properties to customize
the popover and listbox components.
Slots
- base: The main wrapper of the select. This wraps the rest of the slots.
- label: The label of the select.

helperWrapper

slots. - trigger: The trigger of the select. This wraps the label the inner wrapper and the selector icon.
- innerWrapper: The wrapper of the select content. This wraps the start/end content and the select value.
- selectorIcon: The selector icon of the select. This is the icon that rotates when the select is open (
data-open
