I have to add 'file attach' function

when I click ‘add’ button on my page, new window comes out and there is editor.
I have to add ‘attach file’ function on my editor.
Should I have to use ‘vault’ or ‘file selector’?
my dhtmlx version is 5.0.2 and my company use only javascript, instead of html.

can anybody give me vault or file selector example of javascript?
I think there is only html example and when i use https://docs.dhtmlx.com/vault__object_constructor.html ,
I can’t figure out where dhtmlxvault.js and dhtmlxvault.css is. and how to use it.
I’m new to dhtmlx or javascript, so I don’t know a lot of thing.

thank you for reading. :slight_smile:
