DetailsList component doesn't keep selected items

[ozan1535]

I want to use DetailsList component and select multiple items. when I click a button on DetailsList header, I want to delete those selected items. I can get selected items, but the problem is when I click header all selected items disappear. You can also see it on the Fluent UI documentation page:
https://developer.microsoft.com/en-us/fluentui#/controls/web/detailslist/customgroupheaders

Firstly, select some items (or just click Select group), then click Custom header for group 0 . you will see all selected items disappear.

Is there a solution for this problem?

Hi @ozan1535, try setting selectionPreservedOnEmptyClick={true} on DetailsList.
