Two questions about forms

Rails
1

Hi, I’ve two questions about forms:

  • the first is about esthetically, does exist any GUI for forms? like
    (every?) forums and wikis, something that allow the user to click for
    example on B for insert some text in bold, or a button list, table,
    etc…
  • the second is about security, if we accept something (for example a
    description) from users that will be showed it’s better to do an html
    escape with h(), right? but in case i want to use something like
    textilize or a GUI, if i do an html escape also the style inserted by
    textilize will be escaped…so, how can i have a more secure form that
    allow to have some style?

Regarding the first question, many javascript WYSIWYG editors are
available. I found this site on Google:

Regarding your second question, do the html_escape before the
textilize: h(text_from_user).textilize
