 * Hi,
 * I’m trying to create a custom widget. 
   I have an error: “**Uncaught Error: Undefined
   input: undefined**” when I try to add the posts list attribute and “Use Custom
   Fields”. I have already sent a ticket on [https://unitecms.ticksy.com/](https://unitecms.ticksy.com/)
   but it was 3 weeks ago and I still don’t have a solution.
