Yeah sure, you can use sling model to get the parent Page object, and then use the page API from sightly to obtain such values.

I am using constructor injection as the example below as this strategy can also reduce memory consumption of your application, https://sourcedcode.com/blog/aem/aem-sling-model-field-injection-vs-constructor-injection-memory-consumption

Sightly:

<sly data-sly-use.mycomponent="com.mysite.models.components.MyComponent"></sly>
${mycomponent.properties['jcr:title']}

Sling Model:

import com.day.cq.wcm.api.Page;
import org.apache.sling.api.resource.Resource;
import org.apache.sling.models.annotations.DefaultInjectionStrategy;
import org.apache.sling.models.annotations.Model;
import org.apache.sling.models.annotations.injectorspecific.ScriptVariable;

import javax.inject.Inject;
import javax.inject.Named;

@Model(adaptables = Resource.class,
	defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL)
public class MyComponent {

	private Page absParentPage;

	@Inject
	public MyComponent(@ScriptVariable @Named("currentPage") final Page currentPage) {
		Page parentPage = currentPage.getAbsoluteParent(2);
		if (parentPage != null) {
			absParentPage = parentPage;
		}
	}

	public Page getAbsParentPage() {
		return absParentPage;
	}
}

@shibani06 Please try similar to below Code snippet:

${currentPage.parent.properties['jcr:title']}

    Hi @shibani06 

     

    It is not possible to get the value in HTL only, as the absolute parent page can be at "n"th level.

     

    So you need to use Sling Model to retrive the dynamic value.

     

    Returns the absolute parent page. If no page exists at that level, null is returned. Example (this path == /content/geometrixx/en/products)

     | level | returned                        |
 |     0 | /content                        |
 |     1 | /content/geometrixx             |
 |     2 | /content/geometrixx/en          |
 |     3 | /content/geometrixx/en/products |
 |     4 | null                            |

    Hope this helps!

        Sightly:

        <sly data-sly-use.mycomponent="com.mysite.models.components.MyComponent"></sly>
${mycomponent.properties['jcr:title']}

        Sling Model:

        import com.day.cq.wcm.api.Page;
import org.apache.sling.api.resource.Resource;
import org.apache.sling.models.annotations.DefaultInjectionStrategy;
import org.apache.sling.models.annotations.Model;
import org.apache.sling.models.annotations.injectorspecific.ScriptVariable;

import javax.inject.Inject;
import javax.inject.Named;

@Model(adaptables = Resource.class,
	defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL)
public class MyComponent {

	private Page absParentPage;

	@Inject
	public MyComponent(@ScriptVariable @Named("currentPage") final Page currentPage) {
		Page parentPage = currentPage.getAbsoluteParent(2);
		if (parentPage != null) {
			absParentPage = parentPage;
		}
	}

	public Page getAbsParentPage() {
		return absParentPage;
	}
}

          Hi @briankasingli ,

           

          I was looking for a way to get the absolute parent page properties only using sightly but looks like we will have to make use of sling model in order to achieve this.

          Thank you.
