Grouped List always renders expanded.

Hi, is there any way to collapse all the groups in the GroupedList at start, because now after the first render the GroupedList opens all the groups.

Yes, you can make all the groups collapsed by default by settings isCollapsed to true for each IGroup.

Here's a Codepen example: https://codepen.io/seanms/pen/YzdqZMe?editors=0010

There's a lot going on in the Implementation section of GroupedList so it's easy to miss but for more reference check out the implementation for IGroup: https://developer.microsoft.com/en-us/fluentui#/controls/web/groupedlist#implementation
