Sunita,
The jewlerybox themes left panel width is controlled by the apps main config.json (line 10):
    "groups": [
      {
        "visible": false,
        "panel": {
          "uri": "themes/JewelryBoxTheme/panels/LDockablePanel/Panel",
          "position": {
            "left": 0,
            "top": 40,
            "bottom": 0,
            "width": 360,
            "relativeTo": "browser"
          }
        },
