Editable tree has a lot of fields, each field is a Many2One widget (not widget=“selection”).
Each of these widgets can contain a two-character code so the columns are narrow. When editing the widgets, codes are not visible - only “Open the record” and “Clear the field” small buttons can be seen:
“Open the record” and “Clear the field” buttons were not visible in editable tree in Tryton 4.
How can we hide these buttons in Tryton 5?
P.S. Manually changing view tree width is not an option for us.
