What you want is the option TrackedSymbols. By default Manipulate
tracks all symbols in its contents. If you only want some of the
controls to trigger updates, you can specify them. Make sure to use a
delayed rule. Here's an example. Only the last 2 controls trigger an
update in the output:
Manipulate[
{a = a2, b = b2},
{a, 0, 4, 1},
{b, {0, 1, 2, 3, 4}},
{a2, 0, 4, 1},
{b2, {0, 1, 2, 3, 4}},
TrackedSymbols :> {a2, b2}
]
Hope this helps,
