Radio Button Good for selection of a single mutually
exclusive item from a grouped subset of
choices. For example, a set of radio buttons
can be used to obtain gender information
from the web visitor.
File Browser Use the File browser to have your web
visitors upload any file from their
computers. The visitor simply navigates via
a Browse... button and selects a local file of
their choice. Some examples include
uploading pictures, CVs, drawings and
instructions.
CAPTCHA Use as a security check for protecting
against spamming. The form control offers a
random text string for the web visitor to
reproduce in a text box. Passing the check
initiates form submission, which can only be
via Serif Web Resources form submission.
Alternatively, enable the
security check during form
submission instead (see
Submission of forms on
p. 248). Only use one method
when using forms.
Hidden objects can be added as a form control if you use the Form Wizard.
Although the web visitor does not see the field, it is typically used by the web
developer to ensure the data collected has an identifiable string stored with the
visitor's data. An example could be a publish date relating to the web page—
useful for identifying incorrectly working pages.
