title: How to create custom dropdown list in react-native?
body: <p>I almost consume 17 hours, but the answers on what I have searched did not satisfy the exact answer to my question,</p>
  <p><strong>how to create own custom DropdownList in react native?</strong> I already did, the 1st child node which is DropDown (cyan) is work properly, the 2nd child node which is the the List (green) with absolute position but it was not work properly, unless the root parent (red) will also covered the 2nd child node with absolute position, to make it active and clickable, as like what I mention from the picture, <em>Figure 1.0</em></p>

  <p>I set absolute position of the List (green) to make it float from the next child node and the error was persist, the List(parent) was disabled and it cannot click each child items (yellow), unless I set height of the root parent (red) that covered the entire child node but it leads to the next node to adjust the position and do the unexpected layout, like the sample picture <em>Figure 1.1</em></p>
