Select2 to tree
Hello,
I am attempting to add a tree view using the Select2 plugin, and I have tried using the following plugin:
https://github.com/clivezhg/select2-to-tree
While this method works fine on a simple page, I am encountering an error when using it with metronic. The error message is as follows:
Uncaught TypeError: Cannot read properties of null (reading 'trim')
at Utils.copyNonInternalCssClasses (plugins.bundle.js:14111:50)
at SelectionCSS.render (plugins.bundle.js:15579:13)
at DecoratedClass.render (plugins.bundle.js:13872:32)
at new Select2 (plugins.bundle.js:18830:38)
at HTMLSelectElement.<anonymous> (plugins.bundle.js:19737:26)
at Function.each (plugins.bundle.js:385:19)
at jQuery.fn.init.each (plugins.bundle.js:207:17)
at $.fn.select2 (plugins.bundle.js:19734:14)
at $.fn.select2ToTree (select2totree.js:41:21)

I would greatly appreciate any assistance in resolving this issue. Thank you in advance for your help.

Hi,
Have you tried this plugin with the latest version of Select2?
Could you please provide the code used with Metronic using https://gist.github.com/ ? How did you integrate it with Metronic build? Using gulp or webpack? This Select2 Tree plugin looks not updated for the last 2 years and most probably is not compatible with the latest Select2 version.
Regards.
