 * In order to use the loading directive there are few conditions which need to be considered:
 *
 * The item which receives the directive MUST have a parent element and that parent element MUST have an id.
 *
 * Reason: The spinner is added as a child of the parent element because the element which gets the directive must have the opacity set to 0.3 and we don't
 * want that to affect the spinner so the spinner must be on the same level as the child elements which uses the directive, in most cases the <div class="card"> element
 * but the directive can be used also on other elements (see user groups page) if the condition presented above will be respected.
