如何完成可选的子视图？

Question

I have a view with two child views, and want the second view optionally to disappear, that is disabled including the dataBinding, and resize the first view, and vice versa. I need some hints or (pseudo) code how to accomplish this. Thx in advance.

Answer 1

There are quite a few views in SproutCore which do this in some way or another. While it is not the best example, have a look at the experimental select search view .

You are going to need to override createChildViews to set up the bindings manually, so you can also take them down when required.
