84 # Creates a standard text field; use these text fields to input smaller chunks of text like a username
85 # or a search query.

87 # ==== Options
88 # * <tt>:disabled</tt> - If set to true, the user will not be able to use this input.
89 # * <tt>:size</tt> - The number of visible characters that will fit in the input.
90 # * <tt>:maxlength</tt> - The maximum number of characters that the browser will allow the user to enter.
