    You can easily add a column with checkboxes for each row with
    %code g.action_column
    \.
    Normally WiceGrid does not use a form, but its filters work correctly when placed inside a form, so you can use a form to process
    the selected records while keeping the state of the filters. Another way could be reading the selected checkoxes with the help
    of a simple javascript.
  %p
    By default the checkboxes have name
    %code "grid_name[selected][]"
    , but you can change
    %code selected
    to something else with parameter
    %code param_name:  'my-parameter-name'
  %p
    The value of the checkox is the id by default, but you can change it with parameter
    %code object_property:  'some_object_property'
    \.
  %p
    %code select_all_buttons:  false
    hides the "(de)select all" icons, and
    %code html: {class: 'my_class'}
    changes the css class of the checkboxes.
