Customize Export Fields Based On User Input

[MannikJ]

As far as I see it is quite hard to hook in user input to decide which fields to export, because of how the design of the DownloadExcel action.

I know I can overwrite various functions etc. but I have no access to the values of the fields at that time.

So how am I supposed to implement that the user can choose the input fields dynamically?

this is the solution that im using

create a class and extends to DownloadExcel

on handle function

/**
     * @param ActionRequest $request
     * @param Action        $exportable
     *
     * @return array
     */
    public function handle(ActionRequest $request, Action $exportable): array
    {
        $exportable->query = $this->customQuery($request);
        ....
    }

    private function customQuery($request)
    {
        return Model::all();
    }
