Thank you, Bhuwan.
We have a custom dialog on certain page custom component.
I would like to add a text with link under Page Information tab.
If the page is created with the page component, then the custom page component dialog will be open when user clicks on the link.
Is it passible to accomplish this with java/jsp code?
you can refer this http://experience-aem.blogspot.com/2018/09/aem-64-touch-ui-add-view-in-publish-to-editor-page-info-d... for adding new item under page information Tab. And if these items needs to be rendered based on some condition than you can use granite:rendercondition .
you can refer : https://levelup.gitconnected.com/aem-creating-custom-granite-render-conditions-28a21958f420 for adding custom render condition.
