Class CmsSelectWidgetOption

java.lang.Object
  org.opencms.widgets.CmsSelectWidgetOption

public class CmsSelectWidgetOption
extends java.lang.Object

An option of a select type widget.

If options are passed from XML content schema definitions as widget configuration options, the following syntax is used for defining the option values:

value='{text}' default='{true|false}' option='{text}' help='{text}|{more option definitions}

For example:

value='value1' default='true' option='option1' help='help1'|value='value2' option='option2' help='help2'

The elements default, option and help are all optional, only a value must be present in the input. There should be only one default set to true in the input, if more than one is detected, only the first default found is actually used. If no option is given, the value of option defaults to the value of the given value. If no help is given, the default is null.

Shortcut syntax options:

If you don't specify the value key, the value is assumed to start at the first position of an option definition. In this case the value must not be surrounded by the ' chars. Example: value='some value' default='true' can also be written as some value default='true'.

Only if you use the short value definition as described above, a default value can be marked with a * at the end of the value definition. Example: value='some value' default='true' can also be written as some value*.

Only if you use the short value definition as described above, you can also append the option to the value using a :. In this case no ' must surround the option. Please keep in mind that in this case the value itself can not longer contain a : char, since it would then be interpreted as a delimiter. Example: value='some value' option='some option' can also be written as some value:some option.

Any combinations of the above described shortcuts are allowed in the configuration option String. Here are some more examples of valid configuration option Strings:

1*|2|3|4|5|6|7
1 default='true'|2|3|4|5|6|7
value='1' default='true'|value='2'|value='3'
value='1'|2*|value='3'
1*:option text|2|3|4
1* option='option text' help='some'|2|3|4

Please note: If an entry in the configuration String is malformed, this error is silently ignored (but written to the log channel of this class at INFOlevel.
