Hi,
I want to modify the default keyboard focus navigation in LinkTree as
follows:
- The UP and DOWN arrow keys should move the focus to previous/next
tree line
- If the focus is on an expandable node, the LEFT arrow key should
collapse the branch and the RIGHT key should expand the branch
- The TAB key should navigate out of the tree component to the focus
control following the tree and SHIFT-TAB should move the focus to the
focus control preceding the tree
- The tree should remember the last focused node before losing
the focus. When the tree receives the focus again (using the TAB key)
the same node should be selected.
Would it be possible to achieve that functionality in LinkTree using
clientside JavaSript or perhaps with AJAX? Any suggestions would be helpful.
Martin
