Answer by Just code for Keep track of which CheckBox has been Checked

You can use another state object to maitain the checked state of the permissions.

Here is how you add that state

this.state = {      schemas: [],      checkedPermissions: []    }

and here is how you can maitain that state

  CheckPermissions(permissionID) {    const isChecked = this.state.checkedPermissions.some(a => a === permissionID);    if (isChecked) {      this.setState({ checkedPermissions: this.state.checkedPermissions.filter(a => a !== permissionID) })    } else {      const data = this.state.checkedPermissions;      data.push(permissionID);      this.setState({ checkedPermissions: data });    }  }
