I have the following code:
$(\'.wpFolders.co_files\').bind(\'select_node.jstree\', function (event, data) {
getFileById(data.args[0].hash.replace(\'#
After trying so many configurations unsuccessfully, I found a great idea!
By using online photo editor https://pixlr.com/editor/ I have opened icon image file under the path:
jstree\themes\default\32px.png
And I opened the folder icon I want to replace
Replace it easily and save :) I think it is the best after 2 hour struggle.
