Threaded post support for NodeBB

[phenomlab]

@DownPW up to you of course but the browsing users plugin makes several adjustments to element positioning, and without moving the threading toggle outside of that, you’ll always have the issue where the composing user appears on the left because under the old code, the threading toggle shares the same space which causes the alignment issue.

Moving outside of that div is the only way to resolve the issue. There is another way which is to append the topic tools element but that then means that users without adequate permissions will not be able to use the threading toggle at all.

hello @phenomlab

I see this bug with thread view mode :

maybe play with z-index for resolve ?

[phenomlab]

@DownPW yes, that’s definitely a z-index issue.

[DownPW]

After test, seems to be good with add this in JS function in if and else :

$('[component="topic/quickreply/container"]').addClass('threaded'); //test
 
$('[component="topic/quickreply/container"]').removeClass('threaded'); //test

and this to CSS :

[component="topic/quickreply/container"].threaded {
    z-index: -1 !important;
    position: relative;
}

Tell me if this seems correct to you @phenomlab

[phenomlab]

@DownPW seems fine, yes. Any obvious conflict with other elements?

[DownPW]

I haven’t tested everything. this is something to watch out for

[DownPW]

I have the same problem for thread but this time I can’t solve it

[phenomlab]

@DownPW Let me have a look.

Thanks Mark

Besides, my solution above is only partial. It turns out that sometimes I can no longer click to reply to the post via quick Reply. Nothing happens when I click to enter text

It’s a bit the same problem as the previous bug.

It would be more interesting to act on the dropdown menu than the other elements one by one but my attempts are not fruitful for the moment.

We could kill one stone/two birds

[phenomlab]

@DownPW I see the issue. Can you please make the below CSS changes - notice the ones commented out and their replacements (which you should follow)

.page-topic .topic .posts.timeline .timeline-event, .page-topic .topic .posts.timeline > [component="post/placeholder"], .page-topic .topic .posts.timeline > [component=post] {
    border-left: none;
    /* transition: transform 0.3s ease !important; */
    transition: margin-left 0.3s ease, margin-right 0.3s ease !important;
    background: var(--bs-body-bg);
    border-radius: var(--bs-border-radius);
}
 
li[component=post].threaded {
    /* transform: translateX(-100px); */
    /* transition: transform 0.3s ease !important; */
    margin-left: -75px !important;
    transition: margin-left 0.3s ease, margin-right 0.3s ease !important;
}

My expectation is that this will still work (but using margin instead of transform), and also ensure that the reverse dropdown is not being hidden by the [component="post"] elements.

When you use transform on an element, a new stacking order is created for it. As you are transforming a parent which doesn’t have z-index of it’s own, a new stacking order for itself and child elements is created. As a result, the child element with z-index remains below the [component="post"] elements.

If you want to see this in action before applying the CSS, you can remove translateX(-100px) from the li[component=post].threaded class and then try the dropdown menu again. You’ll notice it appears correctly this time, although the content is not being shifted because the translate has been removed.

We replace it with margin which is slightly less performant when it comes to animation, but the nature of NodeBB is to lazyload posts, therefore, this negates the overall impact to the DOM.

Let me know if this works.

[DownPW]

Thats work. Many thanks for resolve
Thanks for the information, I understand better.

Would have a working solution other than mine for this :

[phenomlab]

@DownPW is that still an issue? I can’t replicate that on your dev site?

cache maybe. I have delete the bugfix because not bug fix

[phenomlab]

Yes, I can’t reproduce this.

[DownPW]

I mean bug is present but my bug fix don’t work properly.

test to delete my cache and tell you

[DownPW]

@phenomlab not cache

[phenomlab]

@DownPW PM me the link to the post.

[DownPW]

actually, I noticed that it’s not on all the posts.
it seems that these are the posts where the last response is that of the user (selfpost)

DONE

[phenomlab]

@DownPW I’ll have a look at this later

[DownPW]

no problem.
I have resolve this bug with change/replace this CSS CODE (I have just delete transform directive) :

li.pt-4.self-post:not(.self-post .topic-owner-post).threaded {
   /*transform: translateX(0px) !important;*/
   transition: transform 0.3s ease !important;
   background: var(--bs-body-bg);
   background: var(--bs-body-navbar)!important;
   padding-right: 30px;
   margin-left: 0rem;
   padding-bottom: 0rem !important;
 }

I don’t know if is a goodfix or not.
