I have tested the behaviour, using the provided plunker
example. It seems, however, that the slow rendering observed in plunker
is specific for it. I mean that there are probably some resources that the plunker
needs in order to visualise the code, which is causing the waiting.
I have tested the very same implementation, using the same version as you do, but the issue does not appear. Please give it a try at your end:
If the issue still persists, please send the HTML file, where you use the menu, so we could test the real-life scenario.
I am looking forward to your reply
