+### Selected Items
+
+The `selection` can hold a function to return the items which should get the `selected` class in the results.
+
+Example for switching items on select:
+<!-- prettier-ignore-start -->
+```svelte
+<script>
+
+  function handleSelect(e) {   
+        let i = e.detail.originalIndex;

+<!-- prettier-ignore-end -->
+
+*Hint: Required items should match `selection` and `disabled` to be shown as selected and prevent them from unselection. Further styling may be needed.*
 ### Disable and Filter Items
 
 Use the `filter` to filter Items out and `disable` to disable them in the result set.
+- Filtered items are not part of the results at all.
+- Disabled itesm receive the class `disbaled` and will not fire an `on:select` event.
