look great, but after update no pinned post for me

Cool, thanks! :)

Thanks. LocalStorage entry deleting working fine now.
(For some reason your button wrapper code is missing this time, but I merged it from your former codeshare)

And since you seemed to be a fan of javascript post-processing, I have added some more extra code to toggle the button text accordingly this way.... ;)

if (isCollapsed) {
    $(this).find('.pinned-post-content').hide();  // Klappe den Beitrag ein
    $(this).children(':first')[0].innerText = Ossn.Print('com:pinned:posts:toggle:mark:unread');
} else {
    $(this).children(':first')[0].innerText = Ossn.Print('com:pinned:posts:toggle:mark:read');
}

Okay, I'll make this toggling stuff a configurable option with the next release.

Now the LocalStorage "pinned-post-NUMBER-collapsed" entry is deleted, when using the "unpin" button

The reason for the collasable posts:

Sometimes I pin very large posts and leave them for 2-5 days, depends on importance

When users open the site on mobile, they have to scroll down to see the newest posts - when they read the post, they can collaps it to save space :)

I managed that the existing entry gets deleted, when a new post is pinned - at least a little progress

You forgot to upload dev4? 🙈

The local storage is updated, when another post is pinned, so you always have the pinned-post-id and the "pinned-post-NUMBER-collapsed"

Yes, with my code the entries are not deleted, when post is unpinned, but I don't think this is a big issue with 2 entries

I'll spend some thoughts on how to delete the entries :)

@Dominik
7.2dev4 should fix the FriendsOnline issue

As for collapsing pinned posts:
First of all, thanks for spending some thoughts on my component and providing the code.
Personally, I can't really make friends with first pinning a post to achieve more focus and then collapsing it in the end ... but ok. ;)
The more important: I'm not really happy with the implementation yet, because
1. loading the collapsed posts brings us right back to the flickering (post appears for a short time, then gets hidden) I intentionally tried to avoid with 7.2 by using the hook instead of first collecting that bunch of html and inserting it later
2. there's no code to remove the local storage entry when a post gets unpinned. so after some time your browser will be stuffed up with a lot of orphans - and the memory is not unlimited, see https://stackoverflow.com/questions/13567509/what-happens-when-localstorage-is-full
And since there's no way to access local storage from php directly, you'll always end up with putting the complete html in place first, and then re-ordering it by script - which is an unnecessary overhead - my idea would be using real cookies instead, which could not only deleted by php if necessary, but offer the chance to access them inside the post_collectors loop. This way you could add the right wrapper (collapsed/un-collapsed) already in advance and on loading there's no extra post-processing script needed.

To my opinion the 'FriendsOnline is double' issue should be addressed to the FriendsOnline component.
Long time ago the HTML-Sidebar component had a very similar issue when using a hook, which has been fixed by a javascript solution. Perhaps FriendsOnline can be fixed the same way.

I may find a temporary workaround to remove that friends-onlinge widget on screenswitdt > 992,
but in longer terms the implementation of the newfeed-middle-top hook should be changed to be unconditionally visible. Or another CSS-controlled hook may be added.

I tried something:

I changed the

PinnedPosts/plugins/default/PinnedPosts/posts_collector.php

Now posts are collapsable - was a wish of my users

Uses the local storage to save the post ID and if the pinned post (ID) changes, the localstorage gets updated and the post is enlarged again

Cannot post it here, because it seems to be too long for the comment section "cannot create comment" error

Shared it here:

Maybe you want to take it over for future releases
