What i can do is share with you all my site. And maybe you all can look at the code from the specific pages where i use the show hide, but i believe it is all the same as was posted years ago, which can be found under the resumesection. Now, i know that, not everyone wants to produce the identical solution, as mine is much simpler and only contains text whereas some of you are looking to add a bit more to this, ie galleries, and i don't think the code has ever worked for that.
