When

Panel::create()
                    ->sub([
                        DrillChart::create()->lazyLoading(true)->detailShowable(true),
                    ])

Error

Message: Call undefined detailShowable() method

1- How to get a DrillDown chart to have a detail modal like the other chart classes?

1a- Just found FlexView widget in Dashboard demo. Is it a replacement to DrillDown made the right way for Dashboard?

2- Is it possible to have a button on details modal to export it as PDF or CSV?

BTW, what's the Dashboard v4 w/ FlexView over composer ETA?

Nice, it's very good to know.

And about point 2, is it possible to have a button on details modal to export it as PDF or CSV?

It just shows the loading for a couple seconds and does nothing.

Could this problem be related to it being inside a FlexView within the content function?

When I click an export button, I get this in the Network inspect tool:

{"panels":[],"scripts":["KoolReport.dashboard.dboard.setState({\"ArchiveDocQtdA\":{\"detailModalParams\":[]}});"]}

What I did was:

I have copy/paste the detailModal from TDefaultModal.php and added the buttons

protected function detailModal($params = [])
    {
        $modal = Modal::create();
        $dataView = $this->dataView();
        return $modal
            ->title(Lang::t("Details"))
            ->type("info")
            ->size("lg")
            ->sub([
                Table::create($this->name() . "DetailTable")
                    ->pageSize(10)
                    ->dataSource($dataView->data())
                    ->fields(function () use ($dataView) {
                        //We need to copy columns like this because
                        //of extra fields only be set at creation of fields
                        //The fields here is for Google Chart and
                        //may not be use inside Table
                        return array_map(
                            function ($field) {
                                return $field->clone();
                            },
                            $dataView->fields()
                        );
                    })
            ])
            ->footer([
                Button::create()
                    ->text("Exportar CSV")
                    ->type("primary")
                    ->icon("fa fa-file-csv")
                    ->onClick(
                        Client::showLoader().
                        Client::widget($this->name() . "DetailTable")->exportToCSV()
                    ),
                Button::create()
                    ->text("Exportar PDF")
                    ->type("primary")
                    ->icon("far fa-file-pdf")
                    ->onClick(
                        Client::showLoader().
                        Client::widget($this->name() . "DetailTable")->exportToPDF()
                    ),
                Button::create()
                    ->text(Lang::t("Done"))
                    ->type("success")
                    ->onClick(Modal::hide($modal))
            ]);
    }

And turned feature on:

ArchiveDocQtdA::create()
                                        ->detailShowable(true)
                                        ->pdfExportable(true)
                                        ->csvExportable(true),

Yep, the JS snipet worked there to call showDetail, but it did not changed the status of exportToCSV and exportToPDF, they are still doing nothing after a couple seconds of loading.

I find out what the problem was, I forget the ->pdfExportable(true)->csvExportable(true) in the detailModel Table::create.

It is working now, thanks.
