Getting Started with React Tag Autocomplete

Let’s dive into how you can integrate React Tag Autocomplete into your project.

Installation

First, install the package using npm:

npm install react-tag-autocomplete

Basic Usage

Here’s a simple example to get you started:

import React, { useCallback, useState } from 'react'
import { ReactTags } from 'react-tag-autocomplete'

const suggestions = [
  { value: 1, label: 'React' },
  { value: 2, label: 'JavaScript' },
  { value: 3, label: 'TypeScript' }
]

function TagInput() {
  const [selected, setSelected] = useState([])

  const onAdd = useCallback((newTag) => {
    setSelected([...selected, newTag])
  }, [selected])

  const onDelete = useCallback((tagIndex) => {
    setSelected(selected.filter((_, i) => i !== tagIndex))
  }, [selected])

  return (
    <ReactTags
      labelText="Select technologies"
      selected={selected}
      suggestions={suggestions}
      onAdd={onAdd}
      onDelete={onDelete}
      noOptionsText="No matching technologies"
    />
  )
}

This example creates a basic tag input field with predefined suggestions. Users can add tags from the suggestions or create new ones, and remove tags they’ve added.

Advanced Usage and Customization

React Tag Autocomplete offers extensive customization options to tailor the component to your needs.

Styling

You can override the default styles by passing custom class names:

const customClassNames = {
  root: 'my-root-class',
  rootIsActive: 'my-root-is-active-class',
  selected: 'my-selected-class',
  selectedTag: 'my-selected-tag-class',
  selectedTagName: 'my-selected-tag-name-class',
  search: 'my-search-class',
  searchInput: 'my-search-input-class',
  suggestions: 'my-suggestions-class',
  suggestionActive: 'my-suggestion-active-class',
  suggestionDisabled: 'my-suggestion-disabled-class',
}

<ReactTags
  classNames={customClassNames}
  // ... other props
/>

Custom Rendering

For more control over the component’s appearance, you can provide custom render functions:

const CustomTag = ({ tag, ...props }) => (
  <span className="custom-tag" {...props}>
    {tag.label}
  </span>
)

<ReactTags
  renderTag={CustomTag}
  // ... other props
/>

Validation and New Tag Creation

You can implement custom validation logic for new tags:

const onValidate = (tag) => {
  return tag.label.length >= 3 // Only allow tags with 3 or more characters
}

<ReactTags
  onValidate={onValidate}
  allowNew={true}
  // ... other props
/>

Enhancing User Experience

React Tag Autocomplete provides several props to fine-tune the user experience:

Keyboard Navigation

Enable users to navigate and select tags using the keyboard:

<ReactTags
  activateFirstOption={true}
  delimiterKeys={['Enter', 'Tab']}
  // ... other props
/>

Accessibility

Improve accessibility with custom ARIA labels:

<ReactTags
  labelText="Add technologies"
  ariaAddedText="Technology %value% added"
  ariaDeletedText="Technology %value% removed"
  // ... other props
/>
