XForms items are required when you are creating an XFDL form that contains an XForms data model.
These items are used to contain XForms constructs that do not normally exist in XFDL, such as tables and checkgroups that automatically repeat elements based on the structure of the data model.
attribute uniquely identifies an item. (See
.) Every item sid in a page must be unique. The
element identifies the type of item to create. (For example, <
...> defines the item as a field.) This section contains information about XFDL-defined item types and the options available for each.
Defining an option more than once in an item's definition is not permitted. See
Specifies form-initiated actions that execute automatically.
Specifies a rectangular box on the form. Other items may be positioned on top of boxes (using itemlocation). The purpose of box
items is simply to add visual variety to the form.
Specifies a click button that performs an action when clicked with the mouse or activated with the space bar when it receives the input focus. Buttons can request data from a web server, submit or cancel the form, sign the form, save it to disk, or enclose external files.
With some limitations, the cell item can be used instead of <xforms:select1> or <xforms:select> to populate combobox, list and popup items
Provides a simple check box to record a selected or not selected answer from a user. A selected check box appears filled while a deselected box appears empty.
Creates a group of check boxes. This is useful if you want to create a list of options and allow the user to select some of them. You can configure a checkgroup to allow only one selection, or to allow any number of selections.
Comboboxes act like a hybrid of a field and a popup.
Stores an information object such as an image, a sound, or an enclosed file in an XFDL form.
Creates a text area where users can display and enter one or more lines of data.
Defines a help message that can be used to support various external items in the form.
Defines a static text message or an image to display on the form.
Draws a simple vertical or horizontal line on the form.
Creates a list box from which users can make selections from a list or trigger actions such as enclosing a file or submitting the form.
Creates a popup menu from which users can make selections from a list or trigger actions such as enclosing a file or submitting the form.
Intended for use with one or more other radio
items. A group of radio buttons presents users with a set of mutually exclusive choices. Each radio button represents one choice the user can make.
Creates a group of radio buttons. This is useful if you want to create a list of options from which the user may select only one choice.
Defines a rich text message to display on the form.
Contains a signature and the data necessary to verify the authenticity of a signed form.
Creates a sliding control, similar to a volume control, that lets the user set a value within a specific range. The slider is always horizontal.
Creates space between items on a form. It can be any size specified. It is invisible.
Creates a traditional table of repeated items organized into rows. This is accomplished by creating a template row that includes all of the items that should appear in each row. This row is then linked to the XForms data model.
Allows the definition of a toolbar for a page. A toolbar is a separate and fixed area at the beginning of the page that functions much like a toolbar in a word processing application. Items placed in the toolbar are always visible at the beginning of the form, no matter what portion of the page they are viewing.
Allows form designers to add application specific information to the form definition.
