Selection Arrows

To help you make your selections, you can apply a filter () to limit the items in the list, or type a search string into the search bar. When the filter or search has been applied you can click to move all of the data remaining in the Available list to the Selected list. Any data that isn't visible in the Available list won't be selected.
