Goal
Give AEM admin the flexibility to add additional asset metadata columns in Reporting Console - http://localhost:4502/mnt/overlay/dam/gui/content/reports/reportspage.html
The custom column configuration is stored in cookies, so the configuration is per report and per user
For more information on Assets Reporting check documentation
Thank you ACS Commons for the Generic Lists
For adding columns to Search Results check this post
For adding custom columns to Assets List View check this post
Demo | Package Install | Github
Configure Columns
http://localhost:4502/etc/experience-aem/report-columns.html
Enable Columns
Columns in Report
Report Exported as CSV
Solution
1) Create the extension nt:folder /apps/eaem-asset-reports-dynamic-columns
2) Add the ACS Commons Generic List in nt:folder /apps/eaem-asset-reports-dynamic-columns/components, /apps/eaem-asset-reports-dynamic-columns/templates (available in Package Install if installing the extension)
3) Create sling:Folder /apps/eaem-asset-reports-dynamic-columns/dialog/columns and nt:unstructured /apps/eaem-asset-reports-dynamic-columns/dialog/columns/column with the following properties for creating column html
<?xml version="1.0" encoding="UTF-8"?>
<jcr:root xmlns:sling="http://sling.apache.org/jcr/sling/1.0" xmlns:jcr="http://www.jcp.org/jcr/1.0" xmlns:nt="http://www.jcp.org/jcr/nt/1.0"
jcr:primaryType="nt:unstructured"
sling:resourceType="cq/gui/components/siteadmin/admin/pages/headers/deflt"
class="type small-col"
modalResourceType="granite/ui/components/foundation/form/checkbox"
name="./columns"
sort-selector=".label .eaemCol"
text="eaemCol"
title="eaemCol"/>
4) Create nt:unstructured /apps/eaem-asset-reports-dynamic-columns/dialog/modal with following properties, for showing the column names in Configure Columns modal (set in property columnspath)
<?xml version="1.0" encoding="UTF-8"?>
<jcr:root xmlns:sling="http://sling.apache.org/jcr/sling/1.0" xmlns:jcr="http://www.jcp.org/jcr/1.0" xmlns:nt="http://www.jcp.org/jcr/nt/1.0"
jcr:primaryType="nt:unstructured"
sling:resourceType="dam/gui/coral/components/admin/reports/customcolumnmodal"
columnspath="/apps/eaem-asset-reports-dynamic-columns/dialog/columns"/>
5) Create cq:ClientLibraryFolder /apps/eaem-asset-reports-dynamic-columns/clientlib with categories cq.dam.admin.reports.customcolumns.coral and dependencies underscore
6) Create nt:file /apps/eaem-asset-reports-dynamic-columns/clientlib/js.txt with the following content
dynamic-report-columns.js
7) Create nt:file /apps/eaem-asset-reports-dynamic-columns/clientlib/dynamic-report-columns.js with the following code
