Conditional Statements Regarding Collection Items in Custom Code Fields

The community member is asking if it's possible to use conditional statements regarding Collection Items in a custom code field, specifically inside the head of a collection page. The comments suggest that the community member has a collection that contains either an embedded form, a URL (e.g., to a PDF), or a URL to an external page. The community member would like the collection pages with a URL to have a < meta / > tag, and the pages with the embedded form to open as a normal page without refreshing or forwarding. A workaround suggested is to add a button on the collection page, which requires an extra click, but may be useful if someone stumbles onto the page from a search.
