You need a combination of list_display and modeladmin actions:
<https://docs.djangoproject.com/en/1.4/ref/contrib/admin/#django.contrib.admin.ModelAdmin.list_display>
<https://docs.djangoproject.com/en/1.4/ref/contrib/admin/actions/>

Alternatively, you can use list_editable:
<https://docs.djangoproject.com/en/1.4/ref/contrib/admin/#django.contrib.admin.ModelAdmin.list_editable>

Hi,

thanks for the links, I have look at these docs but I can't figure out how to mix actions with a spreadsheet like presentation :-/

Is it possible to create admin forms like we can standards forms?

Another way I could try is to use filter_horizontal (I like this presentation), but for a m2m relation, just 1 entity can be presented with this widget, not the other side, or I do something wrong?
