Error in console browser: Uncaught TypeError: $ (...). AaDropdownMenu is not a function

Question

I have a project on rails that uses Active_Admin and other plug-ins, I get this error in the browser console. How do I fix this?

application.js

//= require rails-ujs
//= require activestorage
//= require jquery
//= require turbolinks
//= require popper
//= require jquery.slick
//= require_tree .

activ_admin.js.coffe

#= require active_admin/base

and console

$.widget.bridge('aaDropdownMenu', ActiveAdmin.DropdownMenu);

onDOMReady = function() {
  return $('.dropdown_menu').aaDropdownMenu();     // Uncaught TypeError: $(...).aaDropdownMenu is not a function
};

Answer 1

I have exactly the same error. You should change the order in application.js jquery should be in the first place (it's a very important library). I also changed the version of the jquery library.

//= require jquery3
//= require rails-ujs
//= require activestorage
//= require turbolinks 
//= require popper
//= require jquery.slick
//= require_tree .
