Make eleventyExcludeFromCollections pages still accessible for custom collections

[aciccarello]

Is your feature request related to a problem? Please describe.

I have a few types of pages that I currently exclude from collections because I want them to disappear across the site (including sitemap, tag pages, lists of posts). Drafts are my main use case, but I also have a few test posts for checking markup and deleted pages are generated with a stub but otherwise should disappear.

However, I still want to access the drafts and test pages. I currently have to manually curate a drafts page, and I can't use test pages in some tests because I can't get the page data.

Describe the solution you'd like

I would like a collection of only the excluded pages.

eleventyConfig.addCollection('testPosts', (collection) => collection
	.getExcluded()
	.filter((page) => page.data.eleventyExcludeFromCollections == 'test')
);

I'd prefer if using a string as the eleventyExcludeFromCollections would automatically group them but that feels a little out of scope.

{% for posts in collections.excluded.test %}

Describe alternatives you've considered

I've considered not setting eleventyExcludeFromCollections and doing filtering elsewhere, but this has some problems.

• Would not apply to tag collections, so those would need to be filtered, which is hard with pagination
• Custom collections would need to be filtered after glob
• Would need to maintain a new "all" with filtering
• It would be harder to manage all these filters and would be easy to miss something
• Still would need new collections for my test and draft posts

Additional context

I've also looked at #1175 but I don't think that would work as I still don't want content on the tag pages.

I personally think that this could be solved with #955, as you could move all draft posts in a seperate layer under a drafts collection.

I'd personally recommend against a collection called "excluded" that includes the excluded pages (this sentence is hard, I know), but instead recommend adding a new excludedFromCollections variable next to collections.

So instead of

{% for posts in collections.excluded.test %}

you'd use

{% for posts in excludedFromCollections.test %}

That way you could still create a collection called "excluded" as a user.

Naming to be discussed.

What I did in the past to resolve this, was often changing the collection to "hidden_test" so they are actually moved into a separate collection, but that's also not ideal and breaks with directory data files that apply collections.

[aciccarello]

That possibly could work but wouldn't be ideal as it would still require remembering to filter this content elsewhere in my site. I still want all this content excluded from everywhere (main posts list, tag pages, sitemap, etc). I only want to opt-in to accessing these pages on my draft view.
