Thank you for the response.  I provided a link to a page that shows exactly what I want to show, but to explain it in words:

I want to provide a list of teachers, but allow the visitor to click a tag or somehow easily search so that the list only displays what they clicked.  For example, if my website visitor clicks on "Piano," only the piano teachers will be displayed.  If the visitor clicks guitar, only the teachers who teach guitar will be displayed.

It depends what you want to show. In standard, the following are available if you chose the dynamic snippet.

To get more details, you should be clearer about the information you want to show.

good luck
