how to add drop down list in vb?

[msalman]

hey guys,

i apologize in advance if this question have been asked before. I'm trying to create a new page in my vb forum and add few options etc. I've gone through the tutorial on how to create a new page within vb forum and i've been successful so far. I just wondering how can i add textfields, drop down lists (combo box) and buttons etc. I know how to create a form in html and link it to javascript. But i was wondering if there's already built in code then how can i link my code to it? For example, i've seen that in forumjump template, it uses the form and then in one of the optiongroup it calls $forumjumpbits and in other templates i also noticed calls to $somethingbits. Another example is $quickchooserbits or $postbits etc. I was wondering what are these, different classes and how i can create one like this?

thanking in advance
