    React-splitter-layout is a simple split layout for React and modern browsers by Yang Liu (aka zesik).

    The Scry Collective fork adds one feature, and has a focus on keeping all dependencies at the latest versions, at the expense of supporting a wide range of React versions.



    @scrycollective/react-splitter-layout depends on the latest version of React. See package.json for more details.


    $ yarn add @scrycollective/react-splitter-layout


    To run tests, execute test command with yarn: .

    $ yarn test

    To run coverage tests, execute coverage script with yarn.

    $ yarn coverage


    1. Add react-splitter-layout dependency to your code.

      $ yarn add @scrycollective/react-splitter-layout
    2. Include the library into your code and use it.

      import React from 'react'
      import SplitterLayout from '@scrycollective/react-splitter-layout'
      class YourComponent extends React.Component {
        render() {
          return (
              <div>Pane 1</div>
              <div>Pane 2</div>
      export default YourComponent


    Write two parts of the layout as direct children of your SplitterLayout element. SplitterLayout renders the first 2 direct children only if it has more than 2 direct children. SplitterLayout does not render splitter when it has only 1 direct children, and the only direct children occupies all available space.

    The SplitterLayout component supports the following props.

    • customClassName: PropTypes.string

      Custom CSS class name applied to the layout div. You can use this to customize layout style. Refers to the original stylesheet to see what you can customize.

    • vertical: PropTypes.bool

      Determine whether the layout should be a horizontal split or a vertical split. The default value is false.

    • percentage: PropTypes.bool

      Determine whether the width of each pane should be calculated in percentage or by pixels. The default value is false, which means width is calculated in pixels.

    • primaryIndex: PropTypes.number

      Index of the primary pane. Since SplitterLayout supports at most 2 children, only 0 or 1 is allowed. The default value is 0.

      A primary pane is used to show users primary content, while a secondary pane is the other pane. When window size changes and percentage is set to false, primary pane's size is flexible and secondary pane's size is kept unchanged. However, when the window size is not enough for showing both minimal primary pane and minimal secondary pane, the primary pane's size is served first.

    • primaryMinSize: PropTypes.number

      Minimal size of primary pane. The default value is 0.

      When percentage is set to false, this value is pixel size (25 means 25px). When percentage is set to true, this value is percentage (25 means 25%).

    • secondaryMinSize: PropTypes.number

      Minimal size of secondary pane.

    • secondaryInitialSize: PropTypes.number

      Initial size of secondary pane when page loads.

      If this prop is not defined, SplitterLayout tries to split the layout with equal sizes. (Note: equal size may not apply when there are nested layouts.)

    • onSecondarySizeChange: PropTypes.func

      Optional callback function which receives one parameter of type number. It is called when the SplitterLayout component is first mounted, and again whenever the user finishes moving the splitter.

      The purpose of this callback is to provide the ability to save a user positioned splitter as part of an applications state. It is then possible to restore the position using the secondaryInitialSize property. For those using the flow type library, the signature for the callback is ( secondarySize: number ) => void.

    Release History

    • 1.0.0
      • Drop support for React prior to 15.5.4, upgrade all dependencies to latest. Since this is not a backwards compatible change, that is why the version had to go up a major version.
      • Add onSecondarySizeChange callback, to allow saving the splitter position in the store.
    • 0.2.1
      • Fix an incorrect layout when nesting a horizontal splitter inside a vertical one, and now root element of the splitter is absolutely positioned.
    • 0.1.0
      • First proper release.
