title: How to Drag and Drop Custom Widgets?
body: <p>I have created my own custom widget and I want to support internal drag and drop for the widgets.</p>
  
  <p>I have added 4 of my custom widgets in a vertical box layout. Now i want to drag and drop the custom widgets internally. To be more clear, If i drag the last widget and drop it in the first position, then the first widget has to move to the second positon and the last widget (which is dragged) has to move to first position. (same like drag and drop of the items in the List view). Can anyone suggest me a way to drag and drop of the custom widgets.<img src="https://i.stack.imgur.com/OBNDb.png" alt="enter image description here"></p>
