title: Dropdown menu cut-off when using over-flow with scroll
body: <p>I am making a item container which have many item boxes in there, when I hover the item, it will have a drop-down table for item-informations. </p>
  
  <p>The problem here is that I when I set the container to overflow:auto (so that I can store as many boxes as I want) then when I hover at the box, the drop down will be cut-off in a very ridiculous way. What i want is that the dropDown will be all visible, you guys have any trick to make this?</p>
