Edit Drupal Form in "popup" just like it is done in Drupal Views Edit form
I think what you are looking for is the ctools modal functionality.
Without further digging into that - because I think the following tutorial is comprehensive, easy to understand and complete - here is a link that will help you: https://www.deeson.co.uk/labs/insert-form-pop-modal-ctools-and-drupal-7

Some important things you should not forget:


Add the ctools module as dependency.
Add the callback to the menu.
Include the ctools js files on the page where the link to the title popup is.


ctools modal helped me a lot! Give it a try!
