AEM Cloud Service - Multiple Composite Multifields in Content Fragments Editor by Sreekanth Choudry Nalabotu

Abstract

Goal
Adobe Experience Manager 2023.4.12142.20230526T152858Z-230200

Create a Content Fragment Model with Multiple Composite Multifields loaded in Content Fragments Editor. Authors can edit the configuration of a multifield or add additional composite multifields...

Solution
1) Create the project eaem-cf-composite-mf

mvn -B org.apache.maven.plugins:maven-archetype-plugin:3.2.1:generate -D archetypeGroupId=com.adobe.aem
-D archetypeArtifactId=aem-project-archetype -D archetypeVersion=36 -D aemVersion=cloud
-D appTitle="Experience AEM CS CF Composite Multifield" -D appId="eaem-cf-composite-mf" -D groupId="apps.experienceaem.assets"
-D frontendModule=none -D includeExamples=n -D includeDispatcherConfig=n


2) Add a helper thirdparty loadash client library /apps/eaem-cf-composite-mf/lodash with property categories="[eaem.lodash]"



3) For the multiple composite multifields configuration and runtime create a clientlib /apps/eaem-cf-composite-mf/clientlib-mf with categories="[dam.cfm.authoring.contenteditor.v2]" and dependencies="[eaem.lodash]". Add the following code (note the conventions, composite multifield names must end with word CMF and template name with Multifield name and word Template)

(function ($) {
const URL = document.location.pathname,
CFFW = ".coral-Form-fieldwrapper",
MASTER = "master",
CFM_EDITOR_SEL = ".content-fragment-editor",
CMF_SELECTOR = "[data-granite-coral-multifield-name$='CMF']",
CMF_TEMPLATE = "Template";
