+ * - parent : categories having this parent id
+ * - current : current id is used if you are on a category page
+ * - not_empty : if value is 1, category and subcategories must have at least 1 product
+ * - visible : default 1, if you want category not visible put 0
+ * - order : all value available :
+ *      * alpha : sorting by title alphabetical order
+ *      * alpha_reverse : sorting by title alphabetical reverse order
+ *      * reverse : sorting by position descending
+ *      * by default results are sorting by position ascending
+ * - random : if 1, random results. Default value is 0
+ * - exclude : all category id you want to exclude (as for id, an integer or a "string list" can be used)
+ * - limit : number of results. Default value is 10
+ * - offset : at witch id start the search
