I have array with over 200 items, it was showed after loading page 1-2 second. And when scrolling that list has issue on my mobile, it’s slow and lag. Anyone got the same issue? Any suggestion or solution are welcome. Thanks. ---

Could you paste an example of your list definition? Are you using ng-repeat or collection-repeat? The latter is recommended for lists of such size 😉 ---

I’m using ng-repeat You can check my sample in [http://codepen.io/sondn2010/pen/MYyzrO?editors=101](http://codepen.io/sondn2010/pen/MYyzrO?editors=101) One more thing about list, how’s about list with 1000 items. There is a way to load that list when scrolling to bottom or I have to split it and show in other page? And thank for reply me too quickly 🙂 ---

You may want to consider using collection-repeat instead of ng-repeat. It’s a little more work though. One problem with collection-repeat is that it does not support the option buttons that your sample is using. Also, consider using AngularJS’s new one time binding.

would collection-repeat work with pull to refresh and infinite scroll ? ---
