tree 加widget=‘kanban_state_selection’

[hui]

1、如下图，form视图中status字段添加widget=‘kanban_state_selection’，显示的颜色是一样的，如何不同status可以自定义颜色。
2、怎么在tree视图也可以有同样的效果？加widget没效果。

1、这个widget在odoo10的时候还是只是在project模块中自定义的一个widget，而且只是在form，kanban视图中有效果，list视图没有效果的。
2、这个widget不能通用的，odoo11好像可以通用了。

我抄写官方的代码，在我需要的模块自定义了一个status_selection的widget，测试效果可以。主要的js代码如下：

代码中50-59行代码，就是根据自定义的selection的key进行颜色的定义。

这个不是很懂，也不知道哪些是多余的，还有就是这个template用原来的好像不行，复制了一份的。
