Very slow on Tablets

[dustinduse]

I am having an issue where this is very slow on tablets. It causes the page to hang on loading for 10-15 seconds then when you try to open the box it can take 5 seconds before anything happens.

Has anyone had this issue before?. Or is this not designed for such large amounts of options? I have 1409.

Are you experiencing this only on tablet?

I tested my dropdown with 1000. Performance was OK. I’ll look into the performance once more.

[dustinduse]

Yes. On a pc there is no real noticeable hang or lag to open the drop down. Is it possible to render the box serverside?

[sengirab]

I dont think server rendering will fix your lag to be honest.. Its a lightweight angular component. It wont really add much to your bundle size, slow internet could be a cause of your initial load time.

Anyway, https://angular.io/guide/universal might be worth checking out if we’re talking about server side rendering.

Another option would be to make your dropdown async, e.g creating an endpoint to fetch results filling the dropdown. Its explained in #17

Yes, I toyed with async for a little while. I was unable to get it to work properly with my endpoint.
If there is any kind of testing you would like me to do and submit to help you maybe figure out what the issue might be? As for connection, it is NOT a factor.
