Options seem to not be working

[Greg-Freeman]

I am trying to use the enableCollapsibleOptGroups property. When I use it, nothing in my list renders. Am I using this property correctly and is it expected to work? I've tried other properties too and they seem to do the same thing -- I just end up with an empty list. As soon as I remove the property, the dropdown is populated.

<Multiselect ref="myRef" data={this.state.groups} enableCollapsibleOptGroups multiple />

it's an issue in the library here is how ul tag is rendered without options:

and here is how ul is rendered with any option provided:

So it's sending ul element twice for some reason.
