Split

A piece of content can be divided into areas that can be dragged to adjust the width or height.

import { Split } from 'uiw';

@uiw/react-split extracted from the component library uiw can be used alone.

import Split from '@uiw/react-split';

Basic usage

By setting the minWidth style of the child node, you can set the minimum drag width value. By setting the child node style flexBasis style, you can set the proportion width of the default split content.

• Fixed initial width or height, which can be calculated by setting the child node, style width: '80%' to 100% width.
• Drag to the minimum width, you can achieve the effect by setting the child node style minWidth: 30.
• By default, the style width is not set, and a child node style needs to be set to flex: 1 to adapt

import React from 'react';
import Split from '@uiw/react-split';

const Demo = () => (
  <div>
    <Split style={{ height: 100, border: '1px solid #d5d5d5', borderRadius: 3 }}>
      <div style={{ width: '20%', minWidth: 30 }}>
        <iframe
          srcDoc="<div>test</div>"
          style={{ width: '100%', height: '100%' }}
          title="Code Preview"
          sandbox="allow-forms allow-modals allow-pointer-lock allow-popups allow-presentation allow-same-origin allow-scripts"
        />
      </div>
      <div style={{ width: '80%', minWidth: 100 }}>Right Pane</div>
    </Split>
    <Split style={{ height: 100, border: '1px solid #d5d5d5', borderRadius: 3 }}>
      <div style={{ minWidth: 60 }}>test</div>
      <div style={{ minWidth: 80, flex: 1 }}>Right Pane</div>
    </Split>
  </div>
);
export default Demo;

Available for layout

Setting visible={false} disables the drag bar, which can be used for layout.

import React from 'react';
import Split from '@uiw/react-split';

const Demo = () => (
  <div>
    <Split mode="vertical" visible={false}>
      <div style={{ minHeight: 45, background: '#dcdcdc' }}>Header</div>
      <Split visible={false}>
        <div style={{ minWidth: 200, maxWidth: 200, minHeight: 120, background: '#b5b5b5' }}>Sider</div>
        <div style={{ width: '100%', background: '#ececec' }}>Content</div>
      </Split>
      <div style={{ minHeight: 45, background: '#dcdcdc' }}>Footer</div>
    </Split>
    <div style={{ height: 20 }}></div>
    <Split visible={false}>
      <div style={{ minWidth: 200, maxWidth: 200, minHeight: 85, background: '#a9a9a9' }}>Sider</div>
      <Split mode="vertical" visible={false} style={{ width: '100%' }}>
        <div style={{ minHeight: 45, background: '#dcdcdc' }}>Header</div>
        <div style={{ minHeight: 85, background: '#b5b5b5' }}>Content</div>
        <div style={{ minHeight: 45, background: '#dcdcdc' }}>Footer</div>
      </Split>
    </Split>
  </div>
);
export default Demo;

      <div style={{ maxWidth: 100, backgroundColor: '#eaeaea' }}>Left Pane</div>
      <div style={{ flex: 1 }}>Right Pane</div>
    </Split>
    <Split visiable={[4, 5]} style={{ height: 100, border: '1px solid #d5d5d5', borderRadius: 3, marginTop: 10 }}>
      <div style={{ maxWidth: 50, backgroundColor: '#eaeaea' }}>Pane 1</div>
