   @Ovilia I know single `selectedMode` and `select.itemStyle` is about: click node, then it's selected. click again, then it's unselected. How about: click node-A, highlight link-1 and link-2. click node-B, highlight link-3 and link-4.
   
   ```js
   // like this:
   jQuery(function($){
       $(nodeElementA).click(function(){
           // clear highlight
           // highlight linkElement1 and linkElement2
       });
       $(nodeElementB).click(function(){
           // clear highlight
           // highlight linkElement3 and linkElement4
       });
   });
   ```
