问题
I am looking for a way to show a list of wagtail collection as a field in a page (just like it showing when you upload an image). A user can select a collection and I can programmatically filter the images to the selected collection. I am still new to wagtail and I am not sure how should I implement this in code.
Thank you in advance for your help.

So there's a couple ways you can do this. The first, and probably the least-ideal way is to register Collection as a snippet and use a SnippetChooserPanel.
"""Register Collection snippet."""
from wagtail.snippets.models import register_snippet
from wagtail.core.models import Collection
# Register Collections as Snippets so we can use the SnippetChooserPanel to select a collection
register_snippet(Collection)
And then in your model you can use a SnippetChooserPanel, like so (note, this is all untested code)
from django.db import models
from wagtail.core.models import Page
class CustomPage(Page):
    # ...
    collection = models.ForeignKey(
        'wagtailcore.Collection',
        null=True,
        blank=True,
        on_delete=models.SET_NULL,
        related_name='+',
    )
    content_panels = Page.content_panels + [
        # ...
        SnippetChooserPanel('collection'),
    ]
@gasman's comment on the answer has a link to another solution that's much more elegant than mine.

I've managed to do this using wagtail-generic-chooser just following the instructions on the README.md, and using wagtail core Collection model instead of People.
