Hey guys, how can I have like 15 similar metaboxes in my post backend editor and have at first only showing 1 of those boxes and make the following appear only once there is something entered in the previous box. i ask because i do not want to have a bunch of 15 fields, which i only need in some casese and in most cases 2 or 3 would be sufficient. it uneccessarily bloats the entry mask.
.
