title: Adding drag and drop component to iOS app
body: <p>I apologise if this seems very vague but I'm not sure how else to word it.</p>
  
  <p>I am trying to build an ipad app that will let users populate a workspace with tools they need. I need an example of letting a user drag and drop components into the app interface. So for example if i had an app that the user can make a form and I want the user to be able to drag text boxes, lists, radio buttons etc to make the form, how would i go about doing that? The items that i am using will be in a popup menu so that the user drags up and then will see all the items that i need inside that popup. Im just not sure how to let them drag from the popup to the canvas and also be able to reuse the same item (so have 3 or 4 text boxes in the example). Is this possible? Can anyone direct me to a tutorial on this? I have searched but cant find anything. </p>
  
  <p>If this is laid out wrong or is a stupid quest please let me know how to do it, this is my first time posting on here.</p>
  
  <p>Thank you</p>
