Custom background color for selected node
COOLjsTree Professional allows you to customize color for selected node, i.e. node that was just clicked. Here is an example:
var TREE1_FORMAT = [
...
//21. support bgcolor changing for selected node
true,
//22. background color for non-selected and selected node
["white","#FF0000"]
];
Field nr.21 has to be set to "true", and field nr.22 must be the color of background.
