Goal
Adobe Experience Manager 2021.6.5586.20210628T210726Z-210600 (June 28, 2021)
Create a Content Fragment RTE Plugin (RichTextEditor) for Dynamic Variables. Variable is resolved with a value, when the CF is added on a page, fetched from Page Properties. As an example consider Credit Cards and Interest Rates. Interest Rate content is added in AEM as a Content Fragment and the actual interest rate is replaced with value when the CF is added on a specific Card page...
Demo | Package Install | CF Model | Github
Add Dynamic Variable
CF with Dynamic Variables
Dynamic Variable Unresolved
Dynamic Variable Value entered in Page Properties
Dynamic Variable Resolved with Value
Solution
1) Add the plugin /apps/eaem-cs-cf-rte-dyn-var/cfm-dyn-var-plugin/clientlib with categories=[dam.cfm.authoring.contenteditor.v2, eaem-cfm.rte.plugin] and dependencies=eaem.lodash. Add the plugin logic JS file /apps/eaem-cs-cf-rte-dyn-var/cfm-dyn-var-plugin/clientlib/dyn-var-plugin.js with following code...
(function ($, $document) {
var EAEM_PLUGIN_ID = "eaem-dyn-var",

2) Create the plugin modal page /apps/eaem-cs-cf-rte-dyn-var/cfm-dyn-var-plugin/dyn-var-selector with Dynamic Variables configuration...

3) Add a simple Static Template Component in project for testing purposes /apps/eaem-cs-cf-rte-dyn-var/components/basic-htl-page-component
<div style="margin: 10px 25px 10px 25px">
<h2 style="text-align: center">Experience AEM CF Dynamic Variables Demo</h2>
<div data-sly-resource="${'content' @ resourceType='wcm/foundation/components/parsys'}"></div>
</div>
4) Add necessary properties for entering Dynamic Variable values in Page Dialog configuration /apps/eaem-cs-cf-rte-dyn-var/components/basic-htl-page-component/cq:dialog

5) Add a Content Fragment Component for selecting the content fragment, resolving Dynamic Variables and rendering the html /apps/eaem-cs-cf-rte-dyn-var/components/dyn-vars-cf
<div style="width: 100%; border: 1px solid; padding: 20px"
data-sly-use.model="apps.experienceaem.assets.core.models.DynVarsCFModel"
data-sly-test="${model.modalData}">
<div style="color: red">
${model.modalData.eaemHeader}
</div>
<div style="margin-top: 10px">
${model.modalData.eaemContent @context='html'}
</div>
</div>
<div style="width: 100%; height: 30px; margin-top: 30px"
data-sly-use.model="apps.experienceaem.assets.core.models.DynVarsCFModel" data-sly-test="${!model.cfSelectedFrom && wcmmode.edit}">
Content Fragment not configured
</div>
6) Add a sling model apps.experienceaem.assets.core.models.DynVarsCFModel for resolving the Dynamic Variables with Values from Page Properties
package apps.experienceaem.assets.core.models;
import com.adobe.cq.dam.cfm.ContentElement;
import com.adobe.cq.dam.cfm.ContentFragment;

}
public String getCfSelectedFrom() {

}
public Map<String,Object> getModalData(){

}
}
7) Add Design for configuring the Parsys component Allowed Components in /apps/settings/wcm/designs/experience-aem (In Cloud Services for static templates design always comes from configuration in /apps; there is no Design option like in AEM 65 or CS SDK to configure allowed components and stored in for eg. /libs/settings/wcm/designs/default/jcr:content/basic-htl-page-component)
