                  Options
                </DropdownToggle>
        

in here i see the problem i dont have any idea how i must solve the problem. Just down below it says a problem to use "right" keyword.In the console it says "right" property of "DropdownMenu" has been deprecated. Please use "end" instead. for the dropdownMenu right section

                <DropdownMenu right>
                  <DropdownItem>
                    Option 1
                  </DropdownItem>
                  <DropdownItem>
                    Option 2
                  </DropdownItem>
                  <DropdownItem divider />
                  <DropdownItem>
                    Reset
                  </DropdownItem>
                </DropdownMenu>
              </UncontrolledDropdown>
            </Nav>
          </Collapse>
        </Navbar>
      </div>
    );
  }
}
