+#### Loading more options
+
+If you are dynamically loading in more items to the listbox, the very last `<li>` of the `<ul>` should receive the `role="presentation"` attribute and have the [Spinner component](/components/spinners/)  injected into it.
+
+For layout purposes, wrap the spinner in a `<div>` with the class `slds-align_absolute-center` to position the spinner in the middle of the list item, as well as `slds-p-top_medium` to provide the appropiate amount of space for the spinner to be visible.

 Options within a `listbox` can be grouped together under meaningful headings. This is useful if you wish to create separation between 2 or more sets of options within a single `listbox`.
