Programmatically adding Dropdown values do not show up for content fragments

[goonmanian-gooner]

I created a drop down dialog for a content fragment 

ui.content/src/main/content/jcr_root/conf/aem-test/settings/dam/cfm/models/test/.content.xml

 <color jcr:primaryType="nt:unstructured"
                                listOrder="24"
                                valueType="string"
                                showEmptyInReadOnly="true"
                                metaType="enumeration"
                                required="on"
                                name="color"
                                fieldLabel="Color"
                                emptyOption="true"
                                sling:resourceType="granite/ui/components/coral/foundation/form/select"
                                renderReadOnly="false">
                            <optionsMultifield jcr:primaryType="nt:unstructured">
                                <item0 jcr:primaryType="nt:unstructured"
                                       fieldLabel="Error"
                                       fieldValue="error"/>
                                <item1 jcr:primaryType="nt:unstructured"
                                       fieldLabel="Warning"
                                       fieldValue="warning"/>
                                <item2 jcr:primaryType="nt:unstructured"
                                       fieldLabel="Notification"
                                       fieldValue="notification"/>
                            </optionsMultifield>
                            <granite:data jcr:primaryType="nt:unstructured" />
                        </color>

But when building and loading the cfm the dropdown is empty

There are no visible errors in the browser or in the error.log except for a warning

Dynamic data in dropdown for Content Fragment is not possible OOTB as per this blog :
https://blogs.perficient.com/2019/09/06/dynamic-dropdowns-in-aem-content-fragments/

@goonmanian-gooner  Did you try customizing as explained in the blog?

[HeenaMadan · Accepted solution]

There is no extensibility in content fragments to create dynamic drop-downs. Fields are limited and no Api is there to customize fields. But you can overlay the jsp script used to generate the dropdown options from static list. Overlay 

/libs/dam/cfm/admin/components/datasources/optionrenderer/optionrenderer.jsp

and try. Hope this helps!
