Evaluate how to deal with long lists without drawbacks on the user experience

[evilaliv3]

@lukemurray on GlobaLeaks we are evaluating the use of NgHierarchicalSelector inside our form builder to make possible for a user to select options from a hierarchic select-box like the one implemented by NgHierarchicalSelector (https://github.com/globaleaks/GlobaLeaks/issues/1408).

we would have the need to deal with long lists and i'm wondering how this would impact not only from a performance point of view but mostly from the user experience point of view; suppose in fact that one loads a very long list and has to scroll down a lot to find the element he would like to click. have you ever dealt with such a requirement and what would be your suggestion?

Hmm, the way I want to potentially help this is by allowing autocomplete - the ability to type and have the results filtered to potential matches.
