I don't want to copy the page and make the duplicate a modal dialog, that is not what I want. The reason being, if I change anything in the original page, I do not want to go again and replicate it to the dialog pages. I have many such pages like that and it will be an issue for me in the future if any changes are to be done to the original page.
How would I want this?
Best solution would when opening the page using a branch or a link column, I can specify whether to open as a modal dialog or a normal page. I am open to create a flag page item in the original page, which can be used to trigger some kinda javascript.
Any help here would be appreciated.
