您不能拥有任何其他内容的HTML内容（由属性插入）。如果您添加任何项目 html 属性值不会设置/覆盖。但是肯定你可以把任何你想要的东西放在一个手风琴面板上。甚至网格。但是对于这种情况，并且基于最后一个问题，我建议您将视图引用到网格中。您可以通过使用 ComponentQuery

You cannot have html content (inserted by the property) along with any other content. If you add any item the html property value will not set/overriden. But for sure you can place anything you want into one accordion panel. Even a grid. But for that case, and based on the last question, I would recommend you to reference the view into the grid. You may do this simply by using a ComponentQuery

点击事件可以通过使用控制器的功能。

The click events can be applied by using the control function of the controller.

对于您的基本了解：

在ExtJS中，您很少使用纯HTML代码。在大多数情况下，您使用任何类型的组件。全部嵌套在items-array或dockedItem-array中。

适用于控件功能的某些查询示例

在以下中，指控制器本身。

你知道网格的Id（通常你没有这样做）。 Id是由开始的＃

You know the Id of the grid (normally you didn't do this). Id's are marke by a starting #

control({'#yourId': {itemclick: this.onItemclick }});

你知道xtype，只有这个类型的一个实例。您还可以使用xtypes之间的空格来描述路径。

You know the xtype and that there is only one instance of this type. You can also describe a path by using spaces between the xtypes.

control({'grid': {itemclick: this.onItemclick }});

您已经将一个自定义属性设置为网格（可以这样引用任何属性）。这一个是完全兼容的。 我在这种情况下推荐这个。

You have set a custom property to grid (you can refer any property this way). This one is fully compatible the the one above. I recommend this one in your case

control({'grid[customIdent=accordionGrid]': {itemclick: this.onItemclick }});

这只是使用ComponentQueries的一些方法，还有更多。有关更详细的解释，请参考sencha API for ComponentQuery

This are just some ways to use ComponentQueries, there are more. For a more detailed explanation you should refer the sencha API for ComponentQuery

另请注意，每个组件都实现了 up（） 和 down（） 方法也支持ComponentQueries。

Also note that every component implements the up() and down() methods which also support ComponentQueries.

我忘了提到：对于控件，查询严格需要返回一个结果（只有第一个将被采用）另一方面，ComponentQuery可以返回多个结果。

I forgot to mention: For a control the query strictly need to return just one result (only the first one will be taken) a ComponentQuery on the other hand can return multiple results.
