Tags Input

A component that allows users to add tags to an input field.

React
Solid
Vue

Anatomy

To set up the tags input correctly, you'll need to understand its anatomy and how we name its parts.

Each part includes a data-part attribute to help identify them in the DOM.

Examples

Learn how to use the TagsInput component in your project. Let's take a look at the most basic example:

import { TagsInput } from '@ark-ui/react'

export const Basic = () => {
  return (
    <TagsInput.Root>
      <TagsInput.Context>
        {(tagsInput) => (
          <>
            <TagsInput.Label>Frameworks</TagsInput.Label>
            <TagsInput.Control>
              {tagsInput.value.map((value, index) => (
                <TagsInput.Item key={index} index={index} value={value}>
                  <TagsInput.ItemPreview>
                    <TagsInput.ItemText>{value}</TagsInput.ItemText>
                    <TagsInput.ItemDeleteTrigger>Delete</TagsInput.ItemDeleteTrigger>
                  </TagsInput.ItemPreview>
                  <TagsInput.ItemInput />
                </TagsInput.Item>
              ))}
            </TagsInput.Control>
            <TagsInput.Input placeholder="Add Framework" />
            <TagsInput.ClearTrigger>Clear all</TagsInput.ClearTrigger>
          </>
        )}
      </TagsInput.Context>
      <TagsInput.HiddenInput />
    </TagsInput.Root>
  )
}

When the input has an empty value or the caret is at the start position, the tags can be selected by using the arrow left and arrow right keys. When "visual" focus in on any tag:

  • Pressing Enter or double-clicking on the tag will put it in edit mode, allowing the user change its value and press Enter to commit the changes.
  • Pressing Delete or Backspace will delete the tag that has visual focus.

Setting the initial tags

To set the initial tag values, set the defaultValue prop.

import { TagsInput } from '@ark-ui/react'

export const InitialValue = () => {
  return (
    <TagsInput.Root defaultValue={['React', 'Solid', 'Vue']}>
      <TagsInput.Context>
        {(tagsInput) => (
          <>
            <TagsInput.Label>Frameworks</TagsInput.Label>
            <TagsInput.Control>
              {tagsInput.value.map((value, index) => (
                <TagsInput.Item key={index} index={index} value={value}>
                  <TagsInput.ItemInput />
                  <TagsInput.ItemText>{value}</TagsInput.ItemText>
                  <TagsInput.ItemDeleteTrigger>Delete</TagsInput.ItemDeleteTrigger>
                </TagsInput.Item>
              ))}
            </TagsInput.Control>
            <TagsInput.Input placeholder="Add tag" />
            <TagsInput.ClearTrigger>Clear all</TagsInput.ClearTrigger>
          </>
        )}
      </TagsInput.Context>
      <TagsInput.HiddenInput />
    </TagsInput.Root>
  )
}

Limiting the number of tags

To limit the number of tags within the component, you can set the max property to the limit you want. The default value is Infinity.

When the tag reaches the limit, new tags cannot be added except the allowOverflow prop is set to true.

import { TagsInput } from '@ark-ui/react'

export const MaxWithOverflow = () => {
  return (
    <TagsInput.Root max={3} allowOverflow>
      <TagsInput.Context>
        {(tagsInput) => (
          <>
            <TagsInput.Label>Frameworks</TagsInput.Label>
            <TagsInput.Control>
              {tagsInput.value.map((value, index) => (
                <TagsInput.Item key={index} index={index} value={value}>
                  <TagsInput.ItemInput />
                  <TagsInput.ItemText>{value}</TagsInput.ItemText>
                  <TagsInput.ItemDeleteTrigger>Delete</TagsInput.ItemDeleteTrigger>
                </TagsInput.Item>
              ))}
            </TagsInput.Control>
            <TagsInput.Input placeholder="Add Framework" />
            <TagsInput.ClearTrigger>Clear all</TagsInput.ClearTrigger>
          </>
        )}
      </TagsInput.Context>
      <TagsInput.HiddenInput />
    </TagsInput.Root>
  )
}

Validating Tags

Before a tag is added, the validate function is called to determine whether to accept or reject a tag.

A common use-case for validating tags is preventing duplicates or validating the data type.

import { TagsInput } from '@ark-ui/react'

export const Validated = () => {
  return (
    <TagsInput.Root
      validate={(details) => {
        return !details.value.includes(details.inputValue)
      }}
    >
      <TagsInput.Context>
        {(tagsInput) => (
          <>
            <TagsInput.Label>Frameworks</TagsInput.Label>
            <TagsInput.Control>
              {tagsInput.value.map((value, index) => (
                <TagsInput.Item key={index} index={index} value={value}>
                  <TagsInput.ItemInput />
                  <TagsInput.ItemText>{value}</TagsInput.ItemText>
                  <TagsInput.ItemDeleteTrigger>Delete</TagsInput.ItemDeleteTrigger>
                </TagsInput.Item>
              ))}
            </TagsInput.Control>
            <TagsInput.Input placeholder="Add Framework" />
            <TagsInput.ClearTrigger>Clear all</TagsInput.ClearTrigger>
          </>
        )}
      </TagsInput.Context>
      <TagsInput.HiddenInput />
    </TagsInput.Root>
  )
}

Blur behavior

When the tags input is blurred, you can configure the action the component should take by passing the blurBehavior prop.

  • add — Adds the tag to the list of tags.
  • clear — Clears the tags input value.
import { TagsInput } from '@ark-ui/react'

export const BlurBehavior = () => {
  return (
    <TagsInput.Root blurBehavior="add">
      <TagsInput.Context>
        {(tagsInput) => (
          <>
            <TagsInput.Label>Frameworks</TagsInput.Label>
            <TagsInput.Control>
              {tagsInput.value.map((value, index) => (
                <TagsInput.Item key={index} index={index} value={value}>
                  <TagsInput.ItemInput />
                  <TagsInput.ItemText>{value}</TagsInput.ItemText>
                  <TagsInput.ItemDeleteTrigger>Delete</TagsInput.ItemDeleteTrigger>
                </TagsInput.Item>
              ))}
            </TagsInput.Control>
            <TagsInput.Input placeholder="Add Framework" />
            <TagsInput.ClearTrigger>Clear all</TagsInput.ClearTrigger>
          </>
        )}
      </TagsInput.Context>
      <TagsInput.HiddenInput />
    </TagsInput.Root>
  )
}

Paste behavior

To add a tag when a arbitrary value is pasted in the input element, pass the addOnPaste prop.

When a value is pasted, the component will:

  • check if the value is a valid tag based on the validate option
  • split the value by the delimiter option passed
import { TagsInput } from '@ark-ui/react'

export const PasteBehavior = () => {
  return (
    <TagsInput.Root addOnPaste delimiter=",">
      <TagsInput.Context>
        {(tagsInput) => (
          <>
            <TagsInput.Label>Frameworks</TagsInput.Label>
            <TagsInput.Control>
              {tagsInput.value.map((value, index) => (
                <TagsInput.Item key={index} index={index} value={value}>
                  <TagsInput.ItemInput />
                  <TagsInput.ItemText>{value}</TagsInput.ItemText>
                  <TagsInput.ItemDeleteTrigger>Delete</TagsInput.ItemDeleteTrigger>
                </TagsInput.Item>
              ))}
            </TagsInput.Control>
            <TagsInput.Input placeholder="Add Framework" />
            <TagsInput.ClearTrigger>Clear all</TagsInput.ClearTrigger>
          </>
        )}
      </TagsInput.Context>
      <TagsInput.HiddenInput />
    </TagsInput.Root>
  )
}

Disable tag editing

by default the tags can be edited by double-clicking on the tag or focusing on them and pressing Enter. To disable this behavior, pass allowEditTag={false}

import { TagsInput } from '@ark-ui/react'

export const DisabledEditing = () => {
  return (
    <TagsInput.Root editable={false}>
      <TagsInput.Context>
        {(tagsInput) => (
          <>
            <TagsInput.Label>Frameworks</TagsInput.Label>
            <TagsInput.Control>
              {tagsInput.value.map((value, index) => (
                <TagsInput.Item key={index} index={index} value={value}>
                  <TagsInput.ItemInput />
                  <TagsInput.ItemText>{value}</TagsInput.ItemText>
                  <TagsInput.ItemDeleteTrigger>Delete</TagsInput.ItemDeleteTrigger>
                </TagsInput.Item>
              ))}
            </TagsInput.Control>
            <TagsInput.Input placeholder="Add Framework" />
            <TagsInput.ClearTrigger>Clear all</TagsInput.ClearTrigger>
          </>
        )}
      </TagsInput.Context>
      <TagsInput.HiddenInput />
    </TagsInput.Root>
  )
}

Events

During the lifetime of the tags input interaction, here's a list of events we emit:

  • onValueChange — invoked when the tag value changes.
  • onHighlightChange — invoked when a tag has visual focus.
  • onValueInvalid — invoked when the max tag count is reached or the validate function returns false.
import { TagsInput } from '@ark-ui/react'

export const OnEvent = () => {
  return (
    <TagsInput.Root
      onValueChange={(details) => {
        console.log('tags changed to:', details.value)
      }}
      onHighlightChange={(details) => {
        console.log('highlighted tag:', details.highlightedValue)
      }}
      onValueInvalid={(details) => {
        console.log('Invalid!', details.reason)
      }}
      max={3}
      allowOverflow
      validate={(details) => {
        return !details.value.includes(details.inputValue)
      }}
    >
      <TagsInput.Context>
        {(tagsInput) => (
          <>
            <TagsInput.Label>Frameworks</TagsInput.Label>
            <TagsInput.Control>
              {tagsInput.value.map((value, index) => (
                <TagsInput.Item key={index} index={index} value={value}>
                  <TagsInput.ItemInput />
                  <TagsInput.ItemText>{value}</TagsInput.ItemText>
                  <TagsInput.ItemDeleteTrigger>Delete</TagsInput.ItemDeleteTrigger>
                </TagsInput.Item>
              ))}
            </TagsInput.Control>
            <TagsInput.Input placeholder="Add Framework" />
            <TagsInput.ClearTrigger>Clear all</TagsInput.ClearTrigger>
          </>
        )}
      </TagsInput.Context>
      <TagsInput.HiddenInput />
    </TagsInput.Root>
  )
}
