I'm looking for a way to show multi-selection hierarchical component (perhaps a tree) which allow selecting either leafs or folders, with both bubble-up and cascade functionality.
Lets say I use some folder hierarchy:
I'm thinking about 4-states checkbox (select without children -> select with children -> select only children -> unselect).
Any better solution?
I've seen this question but none of the answers fit :(
Edit: relating to each solution in the similar question:
- I cannot use a map as it is not location based hierarchy.
- Adding another leaf for selecting parent only is OK, but it duplicates entries and may increase the tree size.
- Miller columns doesn't solve this issue.
- Adding "select all" button on hover doesn't fix touch devices. Also it looks too complicated to me.
