Install

npm i react-scroll-snap-tabs

Basic Usage

Note that, in order to prevent unexpected behaviors, the order of links and panes should exactly match based on their eventKeys.

import React from 'react'

import Tabs from 'react-scroll-snap-tabs'
import 'react-scroll-snap-tabs/dist/index.css'

const App = () => {
  return (
    <div style={{ width: '400px', height: '100vh', border: '1px solid gray' }}>
      <Tabs eventKeys={['Tab 1', 'Tab 2']}>
        <Tabs.Content paneStyle={{ border: '1px solid gray' }}>
          <Tabs.Pane eventKey='Tab 1'>Content 1</Tabs.Pane>
          <Tabs.Pane eventKey='Tab 2'>Content 2</Tabs.Pane>
        </Tabs.Content>
      </Tabs>
    </div>
  )
}

• activeLinkClass
• activeLinkStyle
• eventKeys
• indicatorClass
• indicatorColor
• indicatorSize
• indicatorStyle
• indicatorParentClass
• indicatorParentStyle
• linkStyle
• linkClass
• onIndicatorMove
• scrollIntoViewEasing
• scrollIntoViewDuration
• scrollIntoViewOffset

Easing Functions

You can use predefined easing functions by providing either "ease-in", "ease-out", or "ease-in-out" string values. If a random string value is provided, the default easing function will be (t) => t (linear). Alternatively, you can provide your own easing function that accepts a number argument between 0 and 1 and returns a number between 0 and 1. You can find more about easing functions on easings.net.

onIndicatorMove Event

When the indicator element moves, the onIndicatorMove callback function is triggered along with the movement.

Event Properties:

Event.progress

It is a fractional value between two snap points that ranges from 0 to 1. The current snap point, representing the current content, is 0, and the target snap point is 1.

Event.target

Returns the indicator element.

Event.isInteracting

Returns a boolean value indicating whether or not the user is interacting with the content area.

Example

import React from 'react'

import Tabs from 'react-scroll-snap-tabs'
import 'react-scroll-snap-tabs/dist/index.css'

const App = () => {
  const width = 10
  const onIndicatorMove = (e) => {

    const timing = (t) => -12 * (t - 0.5) * (t - 0.5) + 4
    const progress = timing(e.progress)
    indicator.style.width = progress * width + 'px'
  }

  return (
    <div style={{ width: '400px', height: '100vh', backgroundColor: '#333' }}>
      <Tabs
        style={{ borderRight: '1px solid gray' }}

How Indicator Works

The tabs include an indicator section that consists of two elements: an indicator and its parent. The parent elemet dynamically adjusts its position based on the active tab, while the indicator represents the actual visible part.

When the user scrolls through the content area, if the layout is 'vertical', the indicator parent adjusts its left and width values to align with the target link element's left and width values. If the layout is 'horizontal', it aligns its top and height values.

Example

import React from 'react'

import Tabs from 'react-scroll-snap-tabs'
import 'react-scroll-snap-tabs/dist/index.css'

const App = () => {
  return (
    <div style={{ width: '400px', height: '100vh', border: '1px solid gray' }}>
      <Tabs
        indicatorParentClass='indicator-parent'
        indicatorParentStyle={{ border: '1px solid red' }}
        indicatorClass='indicator'
        indicatorStyle={{ maxWidth: '75%' }}
        eventKeys={['Tab 1', 'Very Long Tab 2']}
      >
        <Tabs.Content paneStyle={{ border: '1px solid gray' }}>
          <Tabs.Pane eventKey='Tab 1'>Content 1</Tabs.Pane>
          <Tabs.Pane eventKey='Very Long Tab 2'>Content 2</Tabs.Pane>
        </Tabs.Content>
      </Tabs>
    </div>
  )
}

export default App

To provide a visual representation of this behavior, consider the following HTML code, which showcases a rendered indicator parent and indicator elements in a vertical layout application:

<div
  class="indicator-parent"
  style="position: absolute; bottom: 0px; border: 1px solid red; left: 53px; width: 128px;"
>
  <div
    class="indicator"
    style="height: 100%; margin: auto; min-height: 3px; background-color: black; max-width: 75%;"
  ></div>
</div>

Result:

In the provided code, the indicator parent element is represented by the <div> with the class name 'indicator-parent'. It is positioned absolutely and has a red border. Its left and width values are adjusted dynamically based on the corresponding link element's left and width values.

Inside the indicator parent, the indicator element is represented by the <div> with the class name 'indicator'. The background color is black.
