Admin Forum:Text Codings of My Unknowns

I need help on multiple pieces of coding I found.

In lyrics wiki, there are 2 bars that say " [show] ", when it only shows the box, and " [hide] ", when it shows the box and the hidden text. When I copy and paste, it only shows the box. How do I get the text to hide there.

In the spanish Ben 10 Fan Fiction, there is an arrow, which leads to a navigation system. I could try to C.A.P. it but I would need to translate it first. Though, I don't know how to translate coding not in english.

Another is about having a diffrent name in chat when you enter or leave chat. I saw once where someone had a smiley emoticon instead of their user name.

There are 2 more, it's about having the viewer be in text view. Like when there's Forums, there's a box and you type the name of the forum and press a button. I was wondering how I can use that box so users or IPs can type what they like and enter in the box. The other is like what you do in the info box on your user page when go to "When is your birthday?" or something like that. It's where you choose out of 12 months and another where you choose the out of 29-31 days depending on what you chose. I want something similar to you.

Can you help me out?

Thank you,
