PARAMETERS:
1) parent - Optional. Allows you to specify parent category id number
(the id number of each category is displayed in the Control Panel).
You can stack parent categories using pipe character e.g. parent="3|16|28".
2) sibling - Optional. Allows you to specify child category id number
(the id number of each category is displayed in the Control Panel).
Either "parent" or "sibling" parameter MUST BE defined.
3) site - Optional. Allows you to specify site id number.
4) child_categories_sort_by - Optional. Allows you to specify sort order
of child categories. This parameter accepts three values: "name" (child
categories will be sorted by name), "id" (child categories will be sorted
by id number), and "custom" (child categories will be sorted using custom order
as defined in control panel). Default value is "name".
5) child_categories_sort_direction - Optional. Allows you to specify sort direction
of child categories. This parameter accepts two values: "asc" and "desc".
Default value is "asc".
6) show_empty - Optional. Allows you to specify if child categories having no
entries should be displayed or not. This parameter accepts two values: "yes" and "no".
Default value is "no".
7) entries_sort_by - Optional. Allows you to specify sort order of entries.
This parameter accepts two values: "title" and "date". Default value is "date".
8) entries_sort_direction - Optional. Allows you to specify sort direction
of entries. This parameter accepts two values: "asc" and "desc".
Default value is "desc".
9) entries_limit - Optional. Allows you to specify how many entries posted into
child category should be displayed. This parameter accepts as its value an integer
or "none". Default value is "10". Value "none" means that all entries will be
displayed.
10) date_format - Optional. Allows you to specify PHP date format string
(Not ExpressionEngine's date format string!). Default value is "Y-m-d".
11) invalid_input - Optional. Accepts two values: “alert†and “silenceâ€.
Default value is “silenceâ€. If the value is “alertâ€, then in cases when some
parameter’s value is invalid plugin exits and PHP alert is being shown;
if the value is “silenceâ€, then in cases when some parameter’s value
is invalid plugin finishes its work without any alert being shown.
Set this parameter to “alert†for development, and to “silence†- for deployment.
