Edit multiselect field?

Question

So I have a ManyToMany field in my model and Django admin renders it as a multiselect field. It works fine and I have no issues — except that I can't Edit it after creating a record. I tried Del key, mouse right-click, nothing worked. Looks like I have to delete the record and create it again?

This is the field I want to edit. I want to remove one or two of the above items. I'm on Windows.

I think you should try this: [How To Edit ManyToManyField In Django Admin list Display Page?](https://stackoverflow.com/questions/51325438/how-to-edit-manytomanyfield-in-django-admin-list-display-page) — Ashraful Islam, Jun 06 '21 at 17:12
Hold down "Control", or "Command" as the help text says there. This works the same way for unselecting. — Abdul Aziz Barkat, Jun 06 '21 at 17:17
@AbdulAzizBarkat If I hold ```CTRL``` and deselect **all** items, it works. But if I hold ```CTRL``` and deselect just 2 or 3, it doesn't. — Omid Shojaee, Jun 06 '21 at 17:41
Are you logged in as a superuser? If not (staff can also login to admin) the issue may be that you don't have _change_ permission for the related model. — Abdul Aziz Barkat, Jun 06 '21 at 17:51

Well it looks like there's a simpler solution:

(Courtesy of Webdev Hints)

Here's my models:

class Technology(models.Model):
    title = models.CharField(max_length=10)

    def __str__(self):
        return self.title

    class Meta:
        verbose_name_plural = 'Technologies'


class Project(models.Model):
    title = models.CharField(max_length=100)
    description = HTMLField()
    technology = models.ManyToManyField(Technology, related_name='projects')
    image = models.ImageField(upload_to='projects/')

    def __str__(self):
        return self.title

And the solution is to add the following to the admin.py:

@admin.register(Technology)
class TechnologyAdmin(admin.ModelAdmin):
    pass


class TechnologyInline(admin.TabularInline):
    model = Project.technology.through


@admin.register(Project)
class ProjectAdmin(admin.ModelAdmin):
    inlines = (TechnologyInline,)
    exclude = ('technology',)

Now the ManyToMany filed is editable.
