I installed it with npm like described in the documentation.

If i click on the dropdown it takes about 1,4-2 seconds until the dropdown opens...

I am using angular 12.

Can confirm. I'm using version 6 on MacOS 11.6.2 and it takes a while to load. Adding a value to itemsLoadSize fixes the problem for me.

The component also takes very long to initially render, i constantly get warnings like this in my console:

[Violation] 'setTimeout' handler took 103ms zone.js

It is faster though in production mode.
