Name. Specifies the name of the form element created. The default is "c."
items. (optional) A comma-delimited string representing search collections available. The tag retrieves all collections available on the server if the attribute is empty.
Type. (optional) The type of form element used for displaying collections. Valid options are hidden, select, and checkbox. If there is only one collection, the default value is hidden else the default value is checkbox.
Rows. (optional) Represents size if type is select, or number of rows if checkboxes. The default behavior is to satisfy the Cols attribute first. That is, the collections will be listed in columns as specified by the Cols attribute.
Cols. Represents number of columns and is only required if type is checkbox. If Cols and Rows are not specified, the collections will be listed horizontally, that is, in one row.
Defaults. Specifies a comma-delimited string containing 1s or 0s indicating the selection status of the search collections. An item is selected if 1, and not selected if 0. If there is a form action, these values will be retrieved from the form elements.
cssClass. (optional) The class name that will be used in every HTML tag created in this tag. This is particularly useful when the type is checkbox, since an HTML table will be used for the layout. See the sample code below for details.
