I have multiple elements that are being used as the trigger under one class. For example, the "dragHandle" class is my trigger:


<div class="dragHandle"></div>

<div class="dragHandle"></div>

<div class="dragHandle"></div>


<div id="draggableLayer"></div>


This is fine when it is first initialized. All three will drag the "draggableLayer." The problem is, I am dynamically adding more "dragHandle" elements, and they are not seen as triggers after Draggable has initialized on page load. I.e:


<div class="dragHandle"></div>

<div class="dragHandle"></div>

<div class="dragHandle"></div>


<!--  these 2 were added after page load, but don't work like the others do as a trigger -->

<div class="dragHandle"></div>

<div class="dragHandle"></div>


<div id="draggableLayer"></div>


I have tried disabling (and killing) and then enabling the Draggable after adding the the additional trigger elements, but that hasn't worked. Is there a way to destroy and reinitialize the Draggable? Or maybe another way to make it see the additional trigger elements I am dynamically adding?

Hi and welcome to the GreenSock forums,


Draggable only finds the trigger elements upon creation. It doesn't ever re-search the DOM for items with matching selectors.


I'm pretty sure the only way to achieve what you want is to kill() the Draggable and create a new one.



If you need more help in doing that, please provide a simple CodePen demo that makes it easy to add new trigger elements to the DOM.
