Using generated code from FusionTablesLayer Wizard, I am trying to determine how to open the info window onchange. The code below displays the marker perfectly, but I would like the info window to open when a different selection (state) is selected, rather than clicking on the marker to trigger info window. Thanks.
Followup:
Following geocodezip’s remarks below, the following code works well and has given me a great start! Now to use drop down selector rather than sidebar links…
New working code

The only way to open an InfoWindow on a FusionTablesLayer by default is to click on it. To open it from an external event, one option is to create your own InfoWindow. retrieving the content by querying the FusionTable and opening on whatever external stimulus you want.
