Add pulldown menu by text fields

On the administration site you can turn text fields into pull down menu’s. That way you can decide what texts can be chosen by authors (or abstracts). In the example the ‘title’ field in the abstract module is used.
Go to the ‘(Co-)Author data’ page on the admin site. Right-click on the 'Title' field. Go to the 'Field properties' tab and check the box at 'Use input field as pulldown'.

You will see that an extra tab appears, 'Listing'.

On this tab you can add your pulldown answers via the 'Add option' button.

To order the options, click on the 3 grey lines and drag the option to the correct place..

The author has to choose from the pulldown menu. Making the field required prevents authors continuing after choosing the blank.
