Possible to layer a KonvaJS Stage/canvas on top of another canvas?

Newbie question, maybe.

HTML:

<div id="myDiv">
<canvas id="myCanvas" style="display:inline; border: 1px solid #000000;"> </canvas>
</div>


What I want to do is place a KonvaJS Stage on top of (i.e. higher on the z-axis) myCanvas above.

myCanvas

If I use the default code:

var stage = new Konva.Stage(
container: 'myDiv',
width: window.innerWidth,
height: window.innerHeight
);


The Stage is placed inline after myCanvas.

myCanvas

Is there a way to tell Konva to layer its canvas?

You can add a container for the stage into your myDiv:

myDiv

<div id="myDiv">
<canvas id="myCanvas" style="display:inline; border: 1px solid #000000;"></canvas>
<div id="container"></div>
</div>


Then create a stage a place it on top of the absolute position.

const myCanvas = document.getElementById('myCanvas');

const stage = new Konva.Stage(
container: 'container',
width: myCanvas.width,
height: myCanvas.height
);

stage.container().style.position = 'absolute';
stage.container().style.top = '0';
stage.container().style.left = '0';
// add z-index if you need it
