Multinode Treepicker could support multiple root nodes

[harry-gordon]

I have a requirement to allow editors to pick nodes from two "folders" of nodes. Thanks to a bit of help on the forum I built an xPath expression that does what I want:

$current/ancestor::*[name() = 'root' or name() = 'project']/sharedResources

Unfortunately the picker only supports a single root node so only offers the content under the first node.

I think it would be great for pickers to support multiple roots. I can imagine this working in one of two ways:

1. Filtering the tree like a user with multiple starting nodes or;
2. Showing each starting node as a separate tree (@nul800sebastiaan's suggestion).
