How do I make some smilies hidden?
 

I would like to hide some of the smilies from showing on the smilieslist. Is that possible? Can I add a new smiley category and prevent it from showing? I do not want to delete these smilies.

You may be able to edit the code so a certain category doesn't show but the smilies would still work if you used them in a post manually, :mysmilie: for example.

That would be exectly what I wanted, but how can I make the category hidden?

I don't know for sure but there is a template called: smiliepopup_category
Maybe if you put all that code in a conditional...
I never tried but the solution is probably in the smiley templates somewhere.
