"
I am a presenter that gets a list of elements and that allows one to select one (or multiple if the #multipleSelection option is enabled).
Provides a searchable list of classes, and options to configure the search mode (substring search (default), regular expression, exact). The search mode can be combined with case-sensitiveness.

Multiple classes can be selected if the #multipleSelection option is enabled.
