      },
      {
        "kind": "block",
        "type": "controls_whileUntil"
      }
    ]
  };
var workspace = Blockly.inject('blocklyDiv', {toolbox: toolbox});

XML

<xml id="toolbox" style="display: none">
  <block type="controls_if"></block>
  <block type="controls_whileUntil"></block>
</xml>
<script>
  var workspace = Blockly.inject('blocklyDiv',
      {toolbox: document.getElementById('toolbox')});
</script>

XML String

var toolbox = '<xml>' +
    '<block type="controls_if"></block>' +
