XML Object Reference
List
4.7
List
This object represents a selection list comparable to the
<select>
and
<option>
elements
in HTML or WML. A screen can only contain one List object.
There are three types of selection lists: "IMPLICIT", "EXCLUSIVE" and "MULTIPLE". While the
types "IMPLICIT" and "EXCLUSIVE" permit the selection of only one single option, the type
"MULTIPLE" permits the selection of one or more options.
The following attributes are available to the element:
>
The uniqueness of keys and values is not checked in the telephone.
>
If the URL indicated in the
<Url>
element is missing or invalid thereby permitting no
data to be sent to a server, the screen will continue to be displayed unchanged.

IMPLICIT
Default value. As soon as an option has been selected,
the data are sent to the URL specified. As opposed to
the types EXCLUSIVE and IMPLICIT, the user does not
have to press a button or softkey. Only the key/value pair
selected is sent to the server.
EXCLUSIVE
Exactly one option can be selected (radio button func-
tion). On submit, only the key/value pair selected is sent
to the server.
MULTIPLE
One or more options can be selected. On submit, all the
key/value pairs are sent to the server. For selected op-
tions, the value of the
value
attribute is then sent; for
non-selected options, this value is prefixed with
_not
.
Count
(mandatory)
Number of op-
tions
Only as many options as indicated here are displayed.
If the actual number of options exceeds this amount, all
further options are ignored.
0
No options are displayed.
