# Provides a number of methods for creating form tags that doesn't rely on conventions with an object assigned to the template like
# FormHelper does. With the FormTagHelper, you provide the names and values yourself.
#
# NOTE: The html options disabled, readonly, and multiple can all be treated as booleans. So specifying disabled => :true
# will give disabled="disabled".

# Starts a form tag that points the action to an url configured with url_for_options just like

# * :multipart - If set to true, the enctype is set to "multipart/form-data".
