Heres the controller
    [ApiController, Route("api/reports"), Authorize]
    public class ReportsController : Controller
with the methods
    [HttpPost, Route("download")]
    public async Task<IActionResult> Download(string[] ids)
    {
        var cd = new System.Net.Mime.ContentDisposition("attachment") { FileName = "downloads.json" };
        Response.Headers.Add("Content-Disposition", cd.ToString());
        return Ok(await CreateDocumentsOnIds(ids));
    }
    [HttpGet, Route("{id}/download")]
    public async Task<IActionResult> Download(string id)
    {
        var cd = new System.Net.Mime.ContentDisposition("attachment") { FileName = $"document_{id}.json" };
        Response.Headers.Add("Content-Disposition", cd.ToString());
        return Ok(await CreateDocumentOnId(id));
    }
Which works fine for one Id:
    <table class="table is-fullwidth">
        <thead>
            <tr>
                <th>Link</th>
                <th>Dato</th>
            </tr>
        </thead>
        <tbody>
           @foreach (var doc in documents)
           {
              <tr>
                <td><a href="@doc.Url" target="_blank">@doc.Url</a></td>
                <td>@doc.Updated.ToShortDateString()</td>
                <td><a class="button is-link" Color=@Color.Primary href=@($"/api/reports/{doc.Id}/download")>Download</a></td>
              </tr>
           }
       </tbody>
    </table>
But I want the possibility to download several documents as one file. And in order for the controller to be able to create this file, it needs ids of the files. Therefore I somehow need to be able to send an object containing these ids to the controller, from the client memory. Is this possible to do with forms?
