Using Ditto 2.1, you can specify multiple sort order with the
&orderBy parameter, so you could have just one Ditto call, sorting by your checkbox field then by your date field, something like:
[[Ditto? &parents=`2` &display=`5` &tpl=`ditto` &paginate=`1` &orderBy=`anons DESC,createdon DESC` &id=`1`]]
Note the other up-to-date parameters:
&parents can have multiple values, and
&display replacing
&summarize. The snippet will translate
&startId and
&summarize into these anyway.
Unless you are using PHx, or your pages are set not to be cached, you’ll need the Ditto call to be
[!uncached
!] for pagination to work - but if it’s working now, that evidently isn’t a problem.
