Hi everyone,

I’m trying to extend the core Title component core/wcm/components/title/v3/title by adding a dropdown field to its dialog using Sling Resource Merger.

Here is what I have done:

1. Created a proxy component at /apps/myproject/components/title

2. Set sling:resourceSuperType = "core/wcm/components/title/v3/title"

3. Created an overlay dialog at:
/apps/myproject/components/title/_cq_dialog/.content.xml

And I tried adding this dropdown:

<jcr:root
    xmlns:sling="http://sling.apache.org/jcr/sling/1.0"
    xmlns:jcr="http://www.jcp.org/jcr/1.0"
    jcr:primaryType="nt:unstructured"
    sling:resourceSuperType="core/wcm/components/title/v3/title">

    <content jcr:primaryType="nt:unstructured">
        <items jcr:primaryType="nt:unstructured">
            <headingType
                jcr:primaryType="nt:unstructured"
                sling:resourceType="granite/ui/components/coral/foundation/form/select"
                fieldLabel="Heading Type"
                name="./headingType">
                <items jcr:primaryType="nt:unstructured">
                    <h1 jcr:primaryType="nt:unstructured" text="H1" value="h1"/>
                    <h2 jcr:primaryType="nt:unstructured" text="H2" value="h2"/>
                    <h3 jcr:primaryType="nt:unstructured" text="H3" value="h3"/>
                </items>
            </headingType>
        </items>
    </content>
</jcr:root>

But this dropdown not showing in the dialog at all.

Thanks in advance!

Hi @sanaqu,

Please verify the structure of the dialog node where it is nested - Since Sling Resource Merger merges based on matching structure, your dropdown field must be placed in the same path - otherwise, it won’t get picked up.

Example from the above screenshot: Be specific to provide th necessary structured xml.

<jcr:root
    xmlns:jcr="http://www.jcp.org/jcr/1.0"
    xmlns:sling="http://sling.apache.org/jcr/sling/1.0"
    jcr:primaryType="nt:unstructured"
    sling:resourceSuperType="core/wcm/components/title/v3/title">

    <content jcr:primaryType="nt:unstructured">
        <items jcr:primaryType="nt:unstructured">
            <tabs jcr:primaryType="nt:unstructured">
                <items jcr:primaryType="nt:unstructured">
                    <properties jcr:primaryType="nt:unstructured">
                        <items jcr:primaryType="nt:unstructured">
                            <columns jcr:primaryType="nt:unstructured">
                                <items jcr:PrimaryType="nt:unstructured">
                                    <column jcr:primaryType="nt:unstructured">
                                        <items jcr:primaryType="nt:unstructured">

                                            <!-- New Dropdown Field -->
                                            <headingType

                                                fieldLabel="Heading Type"
                                                name="./headingType">

                                                <items jcr:primaryType="nt:unstructured">
                                                    <h1 jcr:primaryType="nt:unstructured" text="H1" value="h1"/>
                                                    <h2 jcr:primaryType="nt:unstructured" text="H2" value="h2"/>
                                                    <h3 jcr:primaryType="nt:unstructured" text="H3" value="h3"/>
                                                </items>
                                            </headingType>

                                        </items>
                                    </column>
                                </items>
                            </columns>
                        </items>
                    </properties>
