Css seems to be missing when combining the plugin with SharePoint framework

[Loevbo]

I've Installed the Plugin with the command npm i jquery-contextmenu and I've told the site that the plugin is required with this require('jquery-contextmenu');.

I've used a simple example from the demo page, and the "menu" do appear on the site, but at the bottom of the page and without any css.

Is this a bug or am i doing something wrong?

The current stable release doesn't really have full support to require with the CSS, You could do two things, there is a jquery.contextMenu.scss which you could include, or add the CSS from the dist folder perhaps.

Slowly working towards a release 3.0 which would modernize quite a few things, but for now this is not something you should wait for.

I encountered the same issue and solved it by doing those three imports:
import jQuery from "jquery"
import '../node_modules/jquery-contextmenu/dist/jquery.contextMenu.min.js'
import '../node_modules/jquery-contextmenu/dist/jquery.contextMenu.min.css'

I then use webpack to bundle the file.
