Help needed in Dropzone.js

Hi devs,

I am looking for some help in dropzone.js, I need to implement multiple dropzones at same time and one main area as well exactly as described below.

1. I have folder structure
2. when page is loaded user see list of folders
3. user should be able to drop files directly into any folder - dropping file into a folder folder should be highlighted maybe change of icon image
4. if user do not want to drop file into any folder he should also be able to drop files anywhere and that will upload into main folder

my above flow is already working I am just stuck at having both option a. dropping files anywhere or dropping files into a specific folder, just small suggestion or help will be appreciated

Regars,
K
