React-Resizable

View the Demo

A simple widget that can be resized via a handle.

You can either use the <Resizable> element directly, or use the much simpler <ResizableBox> element.

See the example and associated code in TestLayout and ResizableBox for more details.

Make sure you use the associated styles in /css/styles.css, as without them, you will have problems with handle placement and visibility.

You can pass options directly to the underlying Draggable instance by using the prop draggableOpts. See the demo for more on this.

Usage

var Resizable = require('react-resizable').Resizable; // or,
var ResizableBox = require('react-resizable').ResizableBox;

...
render: function() {
  return (
    <ResizableBox width={200} height={200} draggableOpts={{...}}
        minConstraints={[100, 100]} maxConstraints={[300, 300]}>
      <span>Contents</span>
    </ResizableBox>
  );
}
