Changes proposed in this pull request:
Before this change, we rendered a "clear" button in the MultiSelect2 example in the docs with a custom element supplied through
tagInputProps={ rightElement: ... }
.This functionality should be provided out of the box, as it's a common use case. So I've added that here in this PR.
The clear button is enabled when an
onClear
callback prop is defined, and omitted when that prop is undefined. It doesn't make much sense to render a button when it's not hooked up to do anything.Reviewers should focus on:
No regression from existing behavior in docs
