Add a product (or a combination)
There are 2 ways to add a product:

A pop-up opens and displays a selection of products matching the search criteria. Click the "Select" button next to the desired product, then click "Add" (it is possible to select multiple products to add them at the same time).
"Increase" or "Decrease" Mode
To make it easier to add or subtract a product quantity, you can click the minus or plus buttons (bottom left) before scanning a product 
Clicking the minus button automatically adds the "-" symbol before the quantity.
The mode is kept until it is changed.
It is possible to mix products in increase or decrease mode.
Update a product quantity (or a combination)
There are 2 ways to update a product quantity:
1. Scan the product barcode as many times as needed (each scan adds 1 to the quantity)
2. Enter the desired quantity in the "Qty In +/-" field (the affected row is automatically moved to the top position).
Note that it is also possible to:
- edit the Purchase Price for each product
- create a negative movement (decrease) by entering the "-" symbol before the quantity
Note: products displayed with a pink background are in 'Offline' status (disabled) in the PrestaShop product sheet.

The module asks the user to confirm the action. If confirmed, all stock movements in the list are applied.
If a quantity was assigned to them, products with a pink background (Offline) are automatically enabled when movements are confirmed.
The list is then cleared.
