                <p>Accordion is a part of easyui framework for jQuery. It lets you define your accordion component on web page more easily.</p>
            </div>
            <div title="Help" data-options="iconCls:'icon-help'" style="padding:10px;">
                <p>The accordion allows you to provide multiple panels and display one or more at a time. Each panel has built-in support for expanding and collapsing. Clicking on a panel header to expand or collapse that panel body. The panel content can be loaded via ajax by specifying a 'href' property. Users can define a panel to be selected. If it is not specified, then the first panel is taken by default.</p>
