Symphony.

Currently I’m using the Expression Field with a “Meta” section to manage all the meta data.

As there is quite a few pages, and typing in the URLs is quite a painful task (or just lazyness!).

I was wondering if there was some way instead of typing them all in, it can populate all entries/pages into a drop down menu, so you can select the entry without needing to type the URL in?

I know of a few otherways, i.e adding the fields to a section, but having all the meta data in one place seems a better idea!

I know your question is about entering the actual data in sections and fields, but there are a few related tips on pulling the data into page templates in this thread about structuring page assets.
