  1. In the site map of Portal Management, go to Content area and select Web Templates. You can sign in to Portal Management from multiple locations. Learn more in Portal Management app overview.
  2. From the Active Web Templates dropdown list, select your knowledge article web template.
  3. On the Web Template page, select the General tab, add the following snippet to the Source field.
                            {{#if relatedAttachments}}
								{{#each relatedAttachments}}
									<li class="note-item">
									{{#if isImage}}
										<a id="kbattachment-{{entityID}}" href="javascript:downloadKbAttachmentFile('kbattachment-{{entityID}}', '{{title}}', {{fileSize}}, '{{fileType}}', '{{downloadBlockUrl}}', '{{initializeDownloadUrl}}')"><span class="glyphicon glyphicon-file" aria-hidden="true"></span>&nbsp;{{title}}</a>
									{{else}}
										<a id="kbattachment-{{entityID}}" title="{{title}}" href="javascript:downloadKbAttachmentFile('kbattachment-{{entityID}}', '{{title}}', {{fileSize}}, '{{fileType}}', '{{downloadBlockUrl}}', '{{initializeDownloadUrl}}')"><span class="glyphicon glyphicon-file" aria-hidden="true"></span>&nbsp;{{title}}</a>
									{{/if}}
									<p class="fragment text-muted">{{{fragment}}}</p>
									</li>
								{{/each}}
							{{/if}}
<script type="text/javascript">
		function downloadKbAttachmentFile(attachmentElementId, fileName, fileSize, mimeType, downloadBlockUrl, initializeUrl) {
					// Download block API supports max 4MB block size
					const blockSizeInBytes = 4096 * 1024;
					const totalNumberOfBlocks = parseInt(fileSize / blockSizeInBytes + 1);
					var fileContinuationToken = "";
					var contentString = "";
					var numberOfBlocksDownloaded = 0;
					var blockNumberToContentMap = {};
					function downloadBlockCallback(i, result) {
						numberOfBlocksDownloaded++;
						blockNumberToContentMap[i] = result;
						if (numberOfBlocksDownloaded == totalNumberOfBlocks) {
							for (var j = 0; j < totalNumberOfBlocks; j++) {
								contentString += blockNumberToContentMap[j];
							}
							var isImage = mimeType.startsWith('image/');
							const attachmentElement = document.getElementById(attachmentElementId);
							if (isImage) {
								const bodyByteString = atob(contentString);
								const bodyBuffer = new ArrayBuffer(bodyByteString.length);
								const bodyView = new Uint8Array(bodyBuffer);
								for (var k = 0; k < bodyByteString.length; k++) {
									bodyView[k] = bodyByteString.charCodeAt(k);
								}
								var imageUrl = URL.createObjectURL(new Blob([bodyBuffer], { type: mimeType }));
								attachmentElement.href = imageUrl;
								attachmentElement.target = "_blank";
							}
							else {
								const linkSource = 'data:' + mimeType + ';base64,' + contentString;
								attachmentElement.href = linkSource;
								attachmentElement.download = fileName;
							}
							attachmentElement.click();
						}
					}
					shell.ajaxSafePost({
						type: 'GET',
						url: initializeUrl,
						success: function (result) {
							fileContinuationToken = encodeURIComponent(result);
							for (var i = 0; i < totalNumberOfBlocks; i++) {
								url = downloadBlockUrl + "&blockNumber=" + i + "&fileContinuationToken=" + fileContinuationToken + "&blockSize=" + blockSizeInBytes;
								var x = downloadBlockCallback.bind(this,i);
								shell.ajaxSafePost({
									type: 'GET',
									url: url,
									success: (result) => { x(result) }
								});
							}
						}
					});
