What is the used Tree in ERPNext

Hello;

Can I know what is the tree that ERPNext used in tree view?
Is it open source tool or was build by ERPNext team?

I think it is part of python library.
Can be found here.

Hope this is what you’re looking for.

Thank you @fkardame
So it is created in python and returned to the browser as html to be displayed in the page, right?

And the grids that is used in the following:

  • List view.
  • Reports.
  • Table.
    From where it is taken originally?
