The method IContentManager.BuildDisplay used to call to the drivers of a ContentItem has an optional groupId argument. I have navigated through the source code but I did not understand exactly what is its use case. It seems to be able to filter shapes, but I'm not sure I understand how.
IContentManager方法。用于调用contrightem驱动程序的BuildDisplay有一个可选的groupId参数。我已经通过了源代码，但是我不知道它的用例到底是什么。它似乎可以过滤形状，但我不确定我能理解。
Could you clarify this for me? Thanks in advance.
你能帮我澄清一下吗?提前谢谢。

Yes, this parameter is used for filtering shapes. You can provide an optional parameter via .OnGroup() method of ContentShape object returned from Display/Editor method of a driver.
是的，这个参数用于过滤形状。可以通过驱动程序的Display/Editor方法返回的. ongroup()方法提供可选参数。
By default it's an empty string. If you provide a groupId parameter in BuildDisplay - only the shapes with that group id specified would be taken into account when building the final output.
默认情况下，它是一个空字符串。如果在BuildDisplay中提供一个groupId参数——在构建最终输出时，只考虑指定了具有该组id的形状。
I found it particularly useful when needed to render the same part differently in different scenarios - returning a Combined result with ContentShape objects (each with different group specified) in it from the driver's Display method.
当需要在不同的场景中以不同的方式呈现相同的部分时，我发现它特别有用——从驱动程序的显示方法中返回一个与ContentShape对象(每个对象具有指定的不同组)组合的结果。
Remember that if you explicitly specify a group in BuildDisplay method - only the shapes with that group set will be used.
请记住，如果在BuildDisplay方法中显式地指定一个组，则只使用具有该组集的形状。
