Selectable: fix mousedown on hierarchical selectable items

[epowers]

1. Create selectable items in a hierarchy.
2. Click on the child item.
3. Bug: the parent is selected if the click is directly on the child selectee.

See: ​http://jsfiddle.net/epowers/a8DY2/

Well this is actually a feature request because the selectable interaction does not support nested selectables.

What is your use case for needing selectables within selectables? This seems a bit odd to me.

[epowers]

The use case is adding selectable to elements in an xhtml editor. User directly selects (multiple) items in the document for drag/resize/copy/etc at different levels of the xml document hierarchy.

Selectable is necessary in this situation because it already coordinates (through ui.widget/ui.mouse) mouse interaction with other components: draggable, droppable, resizable. As well, it provides a lasso tool.

Do you have examples of existing tools that behave this way?

[epowers]

I haven't researched use of selectable in other tools, so I do not know of an existing tool that exercises this problem.

[Scott González]

Well, with only one request for nested selectable support, I don't think we'd want to implement this.
