Hi,

Let me explain better:

• Whenever there's a tree inside a form view (like sale.order.lines) the first field is usually the sequence and allows users to reorder the lines by dragging the cross icon.
• However, on Manufacturing Orders, the trees components and by-products (aka move_raw_ids and move_byproduct_ids) don't have the draggin cross icon.

I've tryed to add the code ≤field name="sequence" widget="handle"/≥ and the results are strange:

• If the code is added as the first column the widget doesn't show up and the user has to manually type the sequence value
• If the code is added after the first few columns the widget icon appears, but it's not clickable.

What am I doing wrong? Was my explanation clear?
