I would like to toggle a loading spinner in the page programmatically. I do not understand example in your "Loading Management" page. Here I found:

const myLoader = document.getElementById('myLoaderID');
const loader = new mdb.LoadingManagement(myLoader);
loader.toggle();

So I created a div in my page with id "myLoaderID", a button with onclick event function calling the code above. But I receive this console error:

TypeError: undefined is not a constructor (evaluating 'new mdb.LoadingManagement(myLoader)')

Am I forgetting to load some module? Please can you explain me what is "MDB UI KIT" and if I have to use:

import { Loading } from 'mdb-ui-kit';

And how have I to use this command? I tried to put this code in JS script but I get an error:

SyntaxError: Unexpected token '{'. import call expects exactly one argument.

Thank you.
