DropDown Positioning absolute element outside of the relative parent container

Question

I'm using ReactJs and Emotion, but I know the problem is related to my CSS

I have a Header structure main ( sidebar content )

That's why I'm having trouble positioning an <ul> tag correctly with position absolute and this error happens: problem gif:

I know it is related to the position: relative of my components or my page structure I already tried everything and I couldn't solve it basically i need my <ul> dropdown to be next to my sidebar like this:

My JSX:

const Tags = () => {
  const [menuItems, setMenuItems] = useState(SideBarTags);

  const showHideDropItem = tag => {
    setMenuItems(items =>
      items.map(item => ({
        ...item,
        Active:
          item.Name === tag.Name ? (tag.Active === true ? false : true) : false
      }))
    );
  };

  return (
    <SideBar.MenuList>
      {menuItems.map((item, index) => (
        <SideBar.ListItem>
          <SideBar.ListWrap>
            <a>
              <item.Icon size={24} />
              <span className="li-name">{item.Name}</span>
            </a>
          </SideBar.ListWrap>
          {item.DropdownItems && (
            <SideBar.ClosedStyled>
              {item.DropdownItems.map(item => (
                <li className="li-closed" key={item.Name}>
                  <FaGhost size={18} />
                  <a onClick={() => console.log(item.Name)}>{item.Name}</a>
                </li>
              ))}
            </SideBar.ClosedStyled>
          )}
        </SideBar.ListItem>
      ))}
    </SideBar.MenuList>
  );
};

export default function App() {
  return (
    <Global.Container>
      <Header.NavBar>
        <Header.LogoSide>
          <img src={Logo} alt="elo Ghost" />
        </Header.LogoSide>
        <div style={{ width: "100%", background: "#eee" }} />
      </Header.NavBar>
      <Global.Main>
        <SideBar.SideBodyWrap>
          <SideBar.DashMenu>
            <Tags />
          </SideBar.DashMenu>
        </SideBar.SideBodyWrap>
        <Content>a</Content>
      </Global.Main>
    </Global.Container>
  );
}

If I'm understanding what you're wanting to achieve correctly, I was able to do it by removing overflow-y:auto from .sidebodywrap and changing left:70% to left:100% in .closedstyled
