I'm having trouble getting landscape to work when exporting to pdf

stycode7

Hi, I'm able to export to pdf, but it always does so in portrait. I tried adding the orientation option but it doesn't seem to be working. What am I doing wrong?

$( document ).ready(function() {
    $('#report').DataTable({
             "processing": true,
             "dom": 'lBfrtip',
             "buttons": [
                {
                    extend: 'collection',
                    text: 'Export',
                orientation: 'landscape',
                    buttons: [
                        'copy',
                        'excel',
                        'csv',
                        'pdf',
                        'print'
                    ]
                }
            ]
            });
    });

You are placing orientation on the wrong element. You need to extend pdf and add the orientation. Like this.

                {
                    extend: 'collection',
                    text: 'PDF',
                    collectionLayout: 'rcoi-dt-pdf-button-group-hack',
                    autoClose: true,
                    buttons: [
                        {
                            extend: 'pdfHtml5',
                            text: 'Portrait',
                            title: 'rCOI Disclosures',
                            exportOptions: {
                                columns: ':visible', orthogonal: 'print'
                            }
                        },
                        {
                            extend: 'pdfHtml5',
                            text: 'Portrait legal',
                            pageSize: 'LEGAL',
                            title: 'rCOI Disclosures',
                            exportOptions: {
                                columns: ':visible', orthogonal: 'print'
                            }
                        },
                        {
                            extend: 'pdfHtml5',
                            text: 'Landscape',
                            orientation: 'landscape',
                            title: 'rCOI Disclosures',
                            exportOptions: {
                                columns: ':visible', orthogonal: 'print'
                            }
                        },
                        {
                            extend: 'pdfHtml5',
                            text: 'Land. legal',
                            pageSize: 'LEGAL',
                            orientation: 'landscape',
                            title: 'rCOI Disclosures',
                            exportOptions: {
                                columns: ':visible', orthogonal: 'print'
                            }
                        }
                    ]
                },
