    react-sticky Build Status

    Make your React components sticky!

    Update (7/2017): No longer actively maintained:

    The 6.0.1 release is the last release maintained by Captivation Software. This means we will not be considering any PR's and/or responding to any issues until a new maintainer is identified. It is highly recommended that you begin transitioning to another sticky library to ensure better support and sustainability. This is obviously less than ideal - sorry for any inconvenience!

    If you are interested in taking over ownership of react-sticky and are willing and able to invest the time the React community deserves, send a message to info@captivationsoftware.com.

    Demos

    Version 6.x Highlights

    • Completely redesigned to support sticky behavior via higher-order component, giving you ultimate control of implementation details
    • Features a minimal yet efficient API
    • Drops support for versions of React < 15.3. If you are using an earlier version of React, continue to use the 5.x series

    Installation

    npm install react-sticky

    Overview & Basic Example

    <Sticky /> elements require a function that returns a React component or DOM node as the only child. When invoked, this child function will be supplied an object with the following properties:

    • isSticky (boolean) - is the element sticky as a result of the current event?
    • wasSticky (boolean) - was the element sticky prior to the current event?
    • distanceFromTop (number) - number of pixels from the top of the Sticky to the nearest StickyContainer's top
    • distanceFromBottom (number) - number of pixels from the bottom of the Sticky to the nearest StickyContainer's bottom
    • calculatedHeight (number) - height of the element returned by this function
    • style (object) - modifiable style attributes to optionally be passed to the element returned by this function

    The Sticky's child function will be called when events occur in the parent StickyContainer, and will serve as the callback to apply your own logic and customizations, with sane style attributes to get you up and running quickly.

    app.js

    import React from 'react';
    import { StickyContainer, Sticky } from 'react-sticky';
    ...
     
    class App extends React.Component ({
      render() {
        return (
          ...
          <StickyContainer>
            ...
            <Sticky>
              {
                ({
                  style,
     
                  // the following are also available but unused in this example
                  isSticky,
                  wasSticky,
                  distanceFromTop,
                  distanceFromBottom,
                  calculatedHeight
                }) => {
                  return (
                    <header style={style}>
                      ...
                    </header>
                  )
                }
              }
            </Sticky>
            ...
          </StickyContainer>
          ...
        );
      },
    });
     

    When the "stickiness" becomes activated, the arguments to the sticky function are modified. Similarly, when deactivated, the arguments will update accordingly.

    <StickyContainer /> Props

    <StickyContainer /> supports all valid <div /> props.

    <Sticky /> Props

    relative (default: false)

    Set relative to true if the <Sticky /> element will be rendered within an overflowing <StickyContainer /> (e.g. style={{ overflowY: 'auto' }}) and you want the <Sticky /> behavior to react to events only within that container.

    When in relative mode, window events will not trigger sticky state changes. Only scrolling within the nearest StickyContainer can trigger sticky state changes.

    topOffset (default: 0)

    Sticky state will be triggered when the top of the element is topOffset pixels from the top of the closest <StickyContainer />. Positive numbers give the impression of a lazy sticky state, whereas negative numbers are more eager in their attachment.

    app.js

    <StickyContainer>
      ...
      <Sticky topOffset={80}>
        { props => (...) }
      </Sticky>
      ...
    </StickyContainer>

    The above would result in an element that becomes sticky once its top is greater than or equal to 80px away from the top of the <StickyContainer />.

    bottomOffset (default: 0)

    Sticky state will be triggered when the bottom of the element is bottomOffset pixels from the bottom of the closest <StickyContainer />.

    app.js

    <StickyContainer>
      ...
      <Sticky bottomOffset={80}>
        { props => (...) }
      </Sticky>
      ...
    </StickyContainer>

    The above would result in an element that ceases to be sticky once its bottom is 80px away from the bottom of the <StickyContainer />.

    disableCompensation (default: false)

    Set disableCompensation to true if you do not want your <Sticky /> to apply padding to a hidden placeholder <div /> to correct "jumpiness" as attachment changes from position:fixed and back.

    app.js

    <StickyContainer>
      ...
      <Sticky disableCompensation>
        { props => (...) }
      </Sticky>
      ...
    </StickyContainer>

    disableHardwareAcceleration (default: false)

    When disableHardwareAcceleration is set to true, the <Sticky /> element will not use hardware acceleration (e.g. transform: translateZ(0)). This setting is not recommended as it negatively impacts the mobile experience, and can usually be avoided by improving the structure of your DOM.

    app.js

    <StickyContainer>
      ...
      <Sticky disableHardwareAcceleration>
        { props => (...) }
      </Sticky>
      ...
    </StickyContainer>
