With Mashup Builder Premium, you can
use more than one feed per page.
By default, feeds are executed in parallel but sometimes, you need to
wait for the result from a previous feed to execute another feed. This
can be done using the Synchronized option.
When
you enable the synchronized option on one of your feeds, remember that
feed order is important.
Feeds that are located after a synchronized feed will wait for it to
answer before triggering themselves.
