Hi Experts,

I am using v1/carousel core component as extending resourceSuperType in my .xml. I want to show hide the entire dialog of the component using show/hide dropdown functionality, as if i select core i need to show all the core dialog and if i select 'custom', i need to show custom dialog. I am having dialog config in cq_dialog and show hide using granite:class but the issue is the core dialog tabs are showing on top of my dropdown selection and if i select my drop down it displays the dialog again below. How to achieve the show/hide properly.

Hi @prasanth_s,

1. Use Two Separate Dialogs and a Wrapper Dropdown

Define two dialogs (one for Core, one for Custom).
In your cq:dialog, keep only the dropdown (selector).
Use granite:rendercondition to include the correct sub-dialog based on dropdown selection.

Example structure:

<cq:dialog
    jcr:primaryType="nt:unstructured"
    xmlns:cq="http://www.day.com/jcr/cq/1.0"
    xmlns:sling="http://sling.apache.org/jcr/sling/1.0"
    xmlns:jcr="http://www.jcp.org/jcr/1.0">

    <content
        jcr:primaryType="nt:unstructured"
        sling:resourceType="granite/ui/components/coral/foundation/container">

        <items jcr:primaryType="nt:unstructured">

            <!-- Dropdown Selector -->
            <dialogType
                sling:resourceType="granite/ui/components/coral/foundation/form/select"
                fieldLabel="Dialog Type"
                name="./dialogType">
                <items jcr:primaryType="nt:unstructured">
                    <core
                        jcr:primaryType="nt:unstructured"
                        text="Core"
                        value="core"/>
                    <custom
                        jcr:primaryType="nt:unstructured"
                        text="Custom"
                        value="custom"/>
                </items>
            </dialogType>

            <!-- Core Dialog Tabs -->
            <coreDialog
                sling:resourceType="myproject/components/coreDialog"
                granite:class="dialog-core"
                granite:rendercondition="myproject/components/renderconditions/isCoreSelected"/>

            <!-- Custom Dialog Tabs -->
            <customDialog
                sling:resourceType="myproject/components/customDialog"
                granite:class="dialog-custom"
                granite:rendercondition="myproject/components/renderconditions/isCustomSelected"/>

        </items>
    </content>
</cq:dialog>

Here, isCoreSelected / isCustomSelected are small rendercondition servlets (can be written in HTL/JavaScript/Java) that check the saved dropdown value and decide which dialog to render.

2. Overlay Core Dialog + Use Tabs Show/Hide

Instead of swapping dialogs, overlay the core cq:dialog.
Add a dropdown in the first tab.
Assign a Granite class like showhide and use data-showhidetarget to toggle core vs custom tabs.

Example:

<dialogType
    sling:resourceType="granite/ui/components/coral/foundation/form/select"
    fieldLabel="Dialog Type"
    name="./dialogType"
    granite:class="cq-dialog-dropdown-showhide"
    cq-dialog-dropdown-showhide-target=".dialog-switch">
    <items>
        <core text="Core" value="core"/>
        <custom text="Custom" value="custom"/>
    </items>
</dialogType>

<coreTab
    jcr:primaryType="nt:unstructured"
    jcr:title="Core Properties"
    granite:class="dialog-switch dialog-core">
    ...
</coreTab>

<customTab
    jcr:primaryType="nt:unstructured"
    jcr:title="Custom Properties"
    granite:class="dialog-switch dialog-custom">
    ...
</customTab>

Then add some clientlib JS to hide/show based on selection.

3. Simpler Alternative (if business allows)

Instead of switching entire dialogs:

Keep the Core dialog as-is.
Add an extra Custom tab (hidden by default).
Toggle visibility of that tab based on dropdown.
This avoids fighting with AEM’s dialog inheritance and is usually the smoothest.

Hi @santoshsai , Thanks for your valuable suggestion, as of now i finalized going with the below approach where i am using custom tab and overlaying core tabs and show hide based on dropdown select, which hides the tab items upon selection.

<content
jcr:primaryType="nt:unstructured"
sling:resourceType="granite/ui/components/coral/foundation/tabs">
<items jcr:primaryType="nt:unstructured">
<variant
jcr:primaryType="nt:unstructured"
jcr:title="Variant"
sling:resourceType="granite/ui/components/coral/foundation/container"
granite:relativePosition="before"
margin="{Boolean}true">
<items jcr:primaryType="nt:unstructured">
<carouselType
jcr:primaryType="nt:unstructured"
sling:resourceType="granite/ui/components/coral/foundation/form/select"
fieldLabel="Carousel Type"
name="./carouselType"
value="carousel"
granite:class="cq-dialog-dropdown-showhide">
<granite:data
jcr:primaryType="nt:unstructured"
cq-dialog-dropdown-showhide-target=".select-showhide-target" />
<items jcr:primaryType="nt:unstructured">
<carousel
jcr:primaryType="nt:unstructured"
text="Carousel"
value="carousel"/>
<custom
jcr:primaryType="nt:unstructured"
text="Custom Carousel"
value="custom"/>
</items>
</carouselType>
</items>
</variant>
<customCarousel
jcr:primaryType="nt:unstructured"
granite:class="hide select-showhide-target">
<granite:data
jcr:primaryType="nt:unstructured"
showhidetargetvalue="custom" />
<items jcr:primaryType="nt:unstructured">
<title
jcr:primaryType="nt:unstructured"
sling:resourceType="granite/ui/components/coral/foundation/form/textfield"
fieldLabel="Title"
name="./title"/>
</items>
</featuredCarousel>
<tabs
jcr:primaryType="nt:unstructured"
jcr:title="Carousel"
sling:resourceSuperType="core/wcm/components/carousel/v1/carousel/cq:dialog/content/items/tabs"
granite:class="hide select-showhide-target">
<granite:data
jcr:primaryType="nt:unstructured"
showhidetargetvalue="carousel" />
</tabs>
</items>
</content>

Thanks
