• Taxonomies
• Type
• Status
• Labels

1. Click Library.
2. Click the Items tab.
3. If you have connected a Taxonomy to an item then you can select which taxonomy you want to filter for. Read this manual if you want to learn more about linking items to a Taxonomy. 
4. Type can be used to select the type of item you want to filter for.
5. The same goes for Status. Read this manual if you want more information about assigning a status to an Item.
6. Labels lets you filter for labels. Refer to this manual if you want more information about creating and assigning labels.
