Single choice toggles

[crystal lagoon]

Hello everyone!

I am trying to implement single choice toggle. A bit of context

I have product edit page.
On product page, there is a tab with all media assigned to the product (repeater)
Each row has FileUpload (media itself)
and few toggles. One of them is "is_cover".

The idea behind it is that only one media can be selected as "Cover"

currently it's implemented as:

Toggle::make('is_cover')
                        ->live()
                        ->afterStateUpdated(function ($state, callable $set, callable $get) {
                            if ($state) {
                                // get all rows
                                $rows = $get('../../media') ?? [];

                                foreach ($rows as $index => $row) {
                                    // turn off all other toggles
                                    if ($row['is_cover'] ?? false) {
                                        if (($row['id'] ?? null) != $get('id')) {
                                            $set("../../media.{$index}.is_cover", false);
                                        }
                                    }
                                }
                            }
                        }),

That works. But it's painfully and unnecessary slow...

I was thinking to use radio, but radio can not be split in repeater. All options must be provided at once in one place. Therefore not suitable in my use - case 🙁

All my attempts to move logic on front-end failed.

I was able to subscribe for event via:
'x-init' and using $watch("state", value => { ... } (maybe there is more efficient way of doing that)
But after than, i was not able to receive items from repeater to toggle off existed records ...
Any documentation or tips, please?
Thanks!

Just make the toggle field ->distinct() in the repeater. Then it will throw a validation error and the user has to fix it.

Thank you very much, @ruby fiber that's exactly what I was looking for!
