Limit/filter snippet result set in the SnippetChooserPanel popup.

[corpulent]

Issue Summary

Is it possible to limit/filter the result set of a snippet in the SnippetChooserPanel? I am using this example http://docs.wagtail.io/en/v1.0/reference/pages/editing_api.html#wagtail.wagtailadmin.edit_handers.wagtail.wagtailsnippets.edit_handlers.SnippetChooserPanel. So in my equivalent of advert, what_it_does (below), I try to add limit_choices_to={description_type=1} to limit the ElementDescriptor snippets in the popup to show only the ones that are of descriptor_type 1. But it always lists ALL ElementDescriptors. Any way to work around this?

    what_it_does = models.ForeignKey(
        'ElementDescriptor',
        null=True,
        blank=True,
        on_delete=models.SET_NULL,
        related_name='+',
        help_text='select a snippet from the what it does type',
        verbose_name='What it does',
        limit_choices_to={'descriptor_type': 1}        
    )

and the way I use is:

    content_panels = Page.content_panels + [
        MultiFieldPanel([
            SnippetChooserPanel('what_it_does')
        ])
    ]

Hi @corpulent,
No, this isn't currently possible - this is covered by #1250.
