I think you may have misunderstood what I mean. That module would be useful for creating the pages for the select field options, but what I'm asking about is importing pages of content where some of the content fields I want to be editable in the admin using select dropdowns.
Take my bibliography_type field, which will have select options like "Book", "Journal Article", "Conference Paper", etc. When that field is set up in ProcessWire using the Page fieldtype those options will be mapped to page IDs (I think) and it is those page IDs that get saved to the database (I think). In my CSV of pages the "Bibliography Type" column will contain the values as text, but I suspect PW is not going to want them in that format. Do I need to find the page IDs for each select option and replace the text in my CSV with the page ID equivalents? Or can I just import my Bibliography Type values as text?
