It would be helpful if you could give us your code to look at. That may
make it easier to explain what you want to achieve as well.
But if I understand what you want (which may not be the case), you could
do something like this:
Assuming a data structure like so,
[{:type :item :pos 1} {:type :sep :pos 2} ... ]
you could choose a component on a case-by-case basis:
(map
#(case (:type %)
:item (om/build item-comp %)
:sep (om/build sep-comp %))
(sort-by :pos collection-of-items-or-separators))
...for example.
