Manipulate and ExclusionsStyle

Question

How can I change ExclusionsStyle for a plot inside Manipulate?

Here's a sample that (though it shouldn't) seems to produce equivalent result to ExlusionsStyle->{None}:

Manipulate[
Plot[{1/(a - x), x/(x - b)}, {x, -10, 10},
Exclusions -> {b, a}, ExclusionsStyle -> {Dashed}], {a, -10, 10}, {b, -10, 10}]

Answer 1

You can give explicit lhs == rhs style exclusions to get dashed lines:

Manipulate[Plot[{1/(a - x), x/(x - b)}, {x, -10, 10}, 
    Exclusions -> {x == b, x == a}, 
    ExclusionsStyle -> Dashed], {{a, 0}, -10, 10}, {{b, 0}, -10, 10}]

Answer 2

Manipulate[
   Plot[{1/(a - x), x/(x - b)}, {x, -10, 10}, Exclusions -> {b, a}, 
         ExclusionsStyle -> {Directive[Thickness[0.03], Orange]}
   ], 
   {a, -10, 10}, {b, -10, 10}
]
