A possible approach: keep the "valid-state" of each component in a map, along
with data which view is currently showing.
Atom for a specific wizard instance:
(def wizard-state {:showing :foo
:panel-states {:foo false
:bar false}}
Then each component can provide a callback by which the wizard can determine
the validity of the currently showing component:
[wizard menu-state
{:id :foo :title "Foo" :component [foo-panel] :callback (fn []
(foo-valid?))}
{:id :bar :title "Bar" :component [bar-panel] :callback (fn []
(bar-valid?)}]
foo-valid? would be a specific function for the foo panel, like
(and (seq (-> @foo-state :field1)) (seq (-> @foo-state :field2)))

This logic should be encoded in the wizard, if the wizard is responsible for
showing the previous or next button. It it is rendering the first element,
disable previous. If the current showing panel is not valid (according to
callback) or if showing the last panel, disable next.
