The following works in FileMaker, you'll have to test it in WebDirect to see if it works there:
If the name comes from a related table, place a copy of the name field from the related table on top of the drop down list field (remove any arrow option). Use behavior settings to deny access to the field when in Browse mode. When you click on the name field, the drop down list pops to the front and deploys. when you select a value, the list disappears back behind the field and the name field now shows the selected name.
And you may want to try the method demonstrated in this file:

Pre FileMaker 12 Users: https://dl.dropbox.com/u/78737945/SimpleNameLookupDemo.fp7
It set ups a working "auto-complete" enabled drop down list for selecting by name but the system still links records by ID.
Phil, thank you for reminding me of that trick. I had used it several months ago, but had to give it up for use in the IWP. FM13 seem to be handling it fine.
OK, I seem to be wrong about WebDirect handling the field overlay well. I just tried it and I can't get it to allow data entry into the overlaid field. :(
