Title: Craft Panel Structure Duplication Issue
ThreadText: # Craft Panel Structure Duplication Issue
  
  (Asked by: username_0 on 2017-03-09)
  
  Having a weird issue here.
  
  I have a structure field inside my section on my panel which is divided up by headings.
  
  The issue I'm having is that when I try to collapse a heading via the panel, it doesn't have any effect. It doesn't collapse and sometimes it makes a duplicate of itself.
  
  Its a hard issue to explain over text so I've created a small video to show the issue in action.

  That's just a quirky byproduct of two subtle features colliding...
  
  **Lazy-loading index** - You don't immediately see the full list of elements. You'll need to keep scrolling down to reveal them all.
  
  **JS-based collapsing** - Collapsing/expanding the tree is a client-side behavior. It uses JS to collapse/expand, then stores the current view in a session cookie.
  
  The behavior is simply a minor local issue... it doesn't affect any actual data in your system. The only real solution is to **refresh the page** when you start seeing the weirdness. Your collapse/expand choices will be remembered, and the items will be reloaded as expected.
