=item * <option />: Allows you to add optional elements to the |
|
resource chooser currently these can be a checkbox, or a text entry |
|
or hidden (see the 'type' attribute below). |
|
the following attributes are supported by this tag: |
|
|
|
=over 4 |
|
|
|
=item * type=control-type : determines the type of control displayed. |
|
This can be one of the following types: 'checkbox' provides a true/false |
|
checkbox. 'text' provides a text entry control. 'hidden' provides a |
|
hidden form element that returns the name of the resource for each |
|
element of the text box. |
|
|
|
=item * text=header-text : provides column header text for the option. |
|
|
|
=item * variable=helpervar : provides a helper variable to contain the |
|
value of the input control for each resource. In general, the result |
|
will be a set of values separated by ||| for the checkbox the value between |
|
the |||'s will either be empty, if the box is not checked, or the resource |
|
name if checked. For the text entry, the values will be the text in the |
|
text box. This could be empty. Hidden elements unconditionally provide |
|
the resource name for each row of the chooser and allow you to therefore |
|
correlate text entries to their resources. |
|
The helper variable can be initialized by the user code to pre-load values |
|
into the controls: |
|
|
|
=over 4 |
|
|
|
|
|
=item * Preloading checkboxes : Set the helper variable to the value you |
|
would have gotten from the control if it had been manually set as desired. |
|
|
|
=item * Preloading text entries : Set the helper variable to triple pipe |
|
separated values where each value is of the form resource-name=value |
|
|
|
=item * Preloading hidden fields : These cannot be pre-loaded and will always |
|
be pipe separated resource names. |
