I know showOnCreate, but my question was related to the show / hide of the elements based on a select field: in the page creation phase the oob logic doesn't seem to work

Thanks Vaibhavi. In the post indicated, the proposed solution is to insert a custom logic. So it is not possible to achieve the goal with just the oob tools?

Is it possible to enable the hide / show oob logic in the page propeties when creating new page?
