[Solved]-Adding target=_blank to link tag in button in react does not open new page but disables it?-Reactjs

The point of using react-router is to render components depending on the url. If you are planning to open the page on a new link just use a regular a element.

const { groupId, unitOffering, userId, role, selectedGroup } = this.state;

const path = `/AssessmentList?groupId=${groupId}&unitOfferingId=${unitOfferingId}&userId=${userId}&role=${role}&groupName=${selectedGroup.group_name}`;

return (
  <a
    href={path}
    target="_blank"
    rel="noopener noreferrer"
    style={{ textDecoration: "none", color: "white" }}>
    Mark
  </a>
);
