Step 2 of the Create Auction Item Bundle flow allows you to filter the display by donation title and/or category. Filtering reduces the number of unbundled donations displayed in the Available Donations box and is useful when combining items of similar title or category. Clicking the button will refresh the page and display only the filtered results.
Clicking the button will refresh the page to the initial state, removing all donations from the Auction Item <ID Number> Bundle pane and returning them to the Available Donations pane.
