Performance issue

[ecotech-yashwant]

Hi ,
It looks really awesome.

BUT , Is there any fixes you did in order to improve the performance while rendering the tree list.
I'm having a scenario and want to render the STATES and underneath each state have COUNTIES tree.
Have 50 states and counties tree item max 70-80 underneath each state to be render.

It works fine, but the page responding very slow. Almost die while rendering 👎
I observed on browser chrome , it give me below message on console while rendering tab where i used tree -list
" [Violation] Added non-passive event listener to a scroll-blocking " ...........ionic.bundle.min.js

any help ?
