we would like to build a search page which is searching publishing pages in SP2013. The search should look for values in three metadata columns. But the search dialog should be cascaded (first choose value of field_1 and choice of field_2 depends on field_1 etc.)
spservices delivers such functionality but this seems to be constructed for listforms. Possible use for a search page?
Is client-side coding the best approach or better develop custom webpart?
