Add and remove item content (mobile)
Some items, such as transport equipment, can hold other items as content. This is useful when several items are handled and moved together.
For example:
- Parent item: Camera kit → Content: Camera, lens, lamp, battery, and memory card
- Parent item: Rack → Content: 10 pairs of shoes, size 10

When can an item contain other items?
In Trail, an item can contain other items in two cases:
- The item type is Case
- The Can have contents setting has been enabled in the item card's details (web version)
When an item can contain other items, the following features are available on its item card:
- Unload case – Removes all content items from the parent item and moves them to the parent item's physical location
- Contents – Displays the items stored inside the parent item

Adding an item as content
- Open the parent item's item card (e.g. a trolley/camera case).
- Tap the scanner icon (blue QR code).
- Scan the QR code of the item you want to add as content.

- From the options, select Add to current item.
- The item has now been added as content.

Tip: Add multiple items as content
You can quickly add several items to a parent item (such as a trolley) by scanning them one after another.
- Enable Add scanned items at the top of the Contents section
- Tap the scanner icon (blue QR code)
- Scan the QR codes of the items one by one
- The camera will remain open until you close it
- The scanned items will appear in the Contents section
- Remember to turn off Add scanned items when finished to prevent accidentally adding items as content during future scans

Unloading content
The Unload case feature allows you to remove all content items from a parent item. The items will automatically be moved to the parent item's physical location.
- Open the parent item's item card
- Select Unload case

- Trail will ask you to confirm that you want to unload the content
- Select Yes
- All content items will be removed from the parent item and moved to its physical location
