smoothsizeswitch v1.0.3

Smooth Size Switch

CSS transitions do not work on element widths or heights when transitioning between two auto sizes. This component allows you to behave as if that restriction didn't exist, by manipulating the elements' max-width and max-height properties when the content is changed.

Idea stolen from here.

Usage example:

Installation:

npm install smoothsizeswitch

Code:

import React from 'react';
import { SmoothSizeSwitch } from 'smoothsizeswitch';

class MyComponent extends React.Component {
  constructor() {
    super();
    this.state = {selectedIndex: 0};
  }

  render() {
    return <div>
      <SmoothSizeSwitch
        style={{
          transition: 'all 250ms ease-out',
          backgroundColor: 'lightBlue'
        }}
        items={[
          <div onClick={() => this.setState({selectedIndex: 1})}>
            <p>123</p>
            <p>123</p>
            <p>123</p>
          </div>,
          <div onClick={() => this.setState({selectedIndex: 0})}>
            <p>234</p>
            <p>234</p>
            <p>234</p>
            <p>234</p>
            <p>234</p>
            <p>234</p>
            <p>234</p>
            <p>234</p>
          </div>,
        ]}
        selectedIndex={this.state.selectedIndex}
      />
    </div>;
  }
}
