For whatever reason all my dropdown menus have disappeared.

I have these dependencies:

  "dependencies": {
    "babel-helper-module-imports": "~7.0.0-beta.3",
    "mdbootstrap": "4.5.5",
    "mdbvue": "~4.5.0",
    "vue": "2.5.17",
    "vue-router": "~3.0.0"
  },
  "devDependencies": {
    "@neutrinojs/vue": "~8.0.0",
    "babel-plugin-transform-runtime": "~6.0.0",
    "babel-preset-stage-2": "~6.0.0",
    "eslint": "~4.19.0",
    "eslint-config-standard": "~11.0.0",
    "eslint-plugin-import": "~2.13.0",
    "eslint-plugin-node": "~7.0.0",
    "eslint-plugin-promise": "~3.8.0",
    "eslint-plugin-standard": "~3.1.0",

    "jquery": "~3.3.0",
    "neutrino": "~8.3.0",
    "webpack": "~3.11.0"
  }

I do have an error besides the usual ones in browser console.

I know understand that this is an issue I should ask on MDBootstrap support - community forum.

[edit]
I should have looked at https://github.com/mdbootstrap/Vue-Bootstrap-with-Material-Design/blob/master/src/docs/NavbarPage.vue and see what changed.
