updated or not?

Hello,

I would like to know if this plugin will be updated or not?
As the version of jquery is no longer supported, I am using a workaround to make this work.

In addition, I have just noticed that the Parent was no longer taken into account.
I have created several child regions and Parent regions.
And in the filter, if the parent is selected, it does not include the children.

Does anyone have the same concern? Do you have a solution?

Thank you in advance.
