Adding an additional item to the grouping

Hello folks! I'm currently trying out this grouping feature in Filament 3 and I've just got a specific question. I have pages that are grouped by a parentPages relation. To be clear: In my case, pages can get a parent page. The grouping works great, but I would like to have the parent page listed in this grouping as well and not individually in a different place of the table. How do I trick the grouping so that the parent page is also included in the grouping? Any idea? I did not find anything in the documentation. Or I have missed it 🫤 //Edit: An example in the screenshot: I would like to be able to find "Third Page" also in the grouping named "Third Page" and not way above the grouping as it is in the screenshot.

Solution:

```php ->prefix(function (Page $record, Table $table): ?Htmlable { if (! static::shouldShowParent($table) && $record->parent) { return new HtmlString('<span style="margin-inline-end: 0.75rem;">&boxur;</span>');...

Are you trying to do something like how Wordpress displays it’s pages?

BastiOP•14mo ago

Well, the last time I saw the Wordpress Backend was 3 years ago. What exactly do you mean? :D

BastiOP•14mo ago

Oh wait, I know what you might mean. That "tree structure" from Wordpress, right? That's more or less what I wanted it to look like

awcodes•14mo ago

Yea. There was a good help thread about this. No real solution though. Be cause it falls apart with filters/searching. Was trying to find it for you but the discord search on mobile is complete crap. I did manage to get something that works similar to how Wordpress is doing it. But it was posted in that thread I can’t find right now.

->prefix(function (Page $record, Table $table): ?Htmlable {
                        if (! static::shouldShowParent($table) && $record->parent) {
                            return new HtmlString('<span style="margin-inline-end: 0.75rem;">&boxur;</span>');
                        }

                        return null;
                    })
                    ->description(function (Page $record, Table $table): ?Htmlable {
                        if (static::shouldShowParent($table) && $record->parent) {
                            return new HtmlString('<span>Parent: ' . Str::of($record->parent)->title() . '</span>');
                        }

                        return null;
                    })

->prefix(function (Page $record, Table $table): ?Htmlable {
                        if (! static::shouldShowParent($table) && $record->parent) {
                            return new HtmlString('<span style="margin-inline-end: 0.75rem;">&boxur;</span>');
                        }

                        return null;
                    })
                    ->description(function (Page $record, Table $table): ?Htmlable {
                        if (static::shouldShowParent($table) && $record->parent) {
                            return new HtmlString('<span>Parent: ' . Str::of($record->parent)->title() . '</span>');
                        }

                        return null;
                    })

public static function shouldShowParent(Table $table): bool {
        $isSearching = $table->hasSearch();
        $isSorting = $table->getSortColumn();
        $hasActiveFilters = collect($table->getFilters())
            ->filter(fn (\Filament\Tables\Filters\BaseFilter $filter) => $filter->getIndicators())
            ->isNotEmpty();

        return $isSearching || $isSorting || $hasActiveFilters;
    }

public static function shouldShowParent(Table $table): bool {
        $isSearching = $table->hasSearch();
        $isSorting = $table->getSortColumn();
        $hasActiveFilters = collect($table->getFilters())
            ->filter(fn (\Filament\Tables\Filters\BaseFilter $filter) => $filter->getIndicators())
            ->isNotEmpty();

        return $isSearching || $isSorting || $hasActiveFilters;
    }

First block goes on the column

This looks like it only affects the title column and not a grouping, right? I would give it a try and it would be an option to me

awcodes•14mo ago

Yea. It won’t work with grouping, that was discussed in that thread. I can’t think of a way to show the grouped parent since they are the same type of record. And that’s how it’s being grouped is by a parent id.

BastiOP•14mo ago

That worked for me, thanks a lot! :) But I guess this is from v2? Because ->prefix() can't output Html for me. Only strings. Or did i miss something?

awcodes•14mo ago

It’s v3 The new HtmlString converts it to a sting Make sure you imported Htmlable and HtmlString

BastiOP•14mo ago

Mh okay thats weird. It converts to a string but the output is not formatted as html. Everything seems right to me

awcodes•14mo ago

Weird.

BastiOP•14mo ago

Oh my mistake. I should have used ->html() in the column xD

awcodes•14mo ago

Makes sense. Sorry. Mine is on BadgeableColumn from a plug-in that is probably handling that by default. Glad it works for you though.

BastiOP•14mo ago

Nevermind. But thanks anyway for your time and help. Have a great night :)

awcodes•14mo ago

You too.
