Threading sublists on list

Question

Suppose I have a list of the form:

list = {a, b, {c, d}, f, {g, h}}

i.e. an element of the list could be another list. I want to 'thread' each element of the sublist, so for the above result I should obtain 4 lists:

{{a,b,c,f,g},{a,b,d,f,g},{a,b,c,f,h},{a,b,d,f,h}}

The list could have arbitrary size and the sublist are arbitrarily distributed. How can I do it?

NOTE: Originally I am trying to map expressions involving AND and OR into lists of the AND elements, e.g.

a && b && ( c || d ) && f && (g || h)

should be mapped to

{{a,b,c,f,g},{a,b,d,f,g},{a,b,c,f,h},{a,b,d,f,h}}

I concluded that substituting AND and OR by list was a good start, hence the above statement of the problem.

Answer 1

Distribute[list, List]

giving

{{a, b, c, f, g}, {a, b, c, f, h}, {a, b, d, f, g}, {a, b, d, f, h}}

Answer 2

Not as elegant as Distribute, but there is also Tuples:

Tuples[List /@ list /. {{x__}} :> {x}]

{{a, b, c, f, g}, {a, b, c, f, h}, {a, b, d, f, g}, {a, b, d, f, h}}

and Outer:

Flatten[Outer[List, ## & @@ (List /@ list /. {{x__}} :> {x})], 4]

{{a, b, c, f, g}, {a, b, c, f, h}, {a, b, d, f, g}, {a, b, d, f, h}}
