Interactive Tree View In Vanilla JavaScript – vanillatree

Preview:

Description:

vanillatree is a simple, collapsible interactive tree view component with context menu support, implemented in vanilla JavaScript.

How to use it:

Include both the vanillatree’s JavaScript and CSS files on the html page.

<link href="vanillatree.css" rel="stylesheet">
<script src="vanillatree.js"></script>

Create a container where you want to present the tree view.

<main></main>

Initialize the tree view and set the right click context menu as this:

var main = document.querySelector( 'main' ),
    tree = new VanillaTree( main, {
      contextmenu: [{
          label: 'Menu 1',
          action: function(id) {
            alert('Menu 1 ' + id);
          }
        }, {
          label: 'Menu 2',
          action: function(id) {
            alert('Menu 2 ' + id);
          }
        }]
    });

Add custom nodes to the tree view.

tree.add({
  label: 'Label A',
  id: 'a',
  opened: true
});
tree.add({
  label: 'Label B',
  id: 'b'
});
tree.add({
  label: 'Label A.A',
  parent: 'a',
  id: 'a.a',
  opened: true,
  selected: true
});
tree.add({
  label: 'Label A.A.A',
  parent: 'a.a'
});
tree.add({
  label: 'Label A.A.B',
  parent: 'a.a'
});
tree.add({
  label: 'Label B.A',
  parent: 'b'
});
