How to Expand the Palette using External Button in JavaScript Diagram?

This article explains how to expand the palette using an external button in JavaScript Diagram. In our Syncfusion_® JavaScript Diagram, symbol palettes can be expanded or collapsed by clicking the palette header. To control this behavior using an external button, update the expanded property of the palettes to true or false when the button is clicked.

<button id="collapseFlow">Collapse Flowshapses</button>
<button id="expandFlow">Expand Flowshapses</button> 

document.getElementById('collapseFlow').onclick = function () {
 palette.palettes[0].expanded = false;
 palette.dataBind();
};
document.getElementById('expandFlow').onclick = function () {
 palette.palettes[0].expanded = true;
 palette.dataBind();
};
