有没有办法在optionValue中显示多个字段名称？

<g:select name="id" from="${Books.list()}" optionKey="id"
          value="" optionValue="name"
          noSelection="${['null':'Select Publisher...']}"/>

EXPE:

<g:select name="id" from="${Books.list()}" optionKey="id"
          value="" optionValue="name and author"
          noSelection="${['null':'Select Publisher...']}"/>
