JS Loading Indicator

In your JS File, import ElementLoadingIndicatorUtil. When you start typing import ElementLoadingIn..., PHPStorm should give you the correct path as a suggestion.

Then, to add an Indicator:

ElementLoadingIndicatorUtil.create(<HTMLELEMENT>);

<HTMLELEMENT> is here - of course - the HtmlElement you want to add this to.

To close it, call:

ElementLoadingIndicatorUtil.remove(<HTMLELEMENT>);

That's it!
