php - Split Opencart Sitemap into multiple columns -

i using opencart 2.0.1.1 , in information/sitemap, categories in site map listed in 1 column , since have lots of categories generating long list in 1 column.

i trying figure out if can split categories in multiple columns make good. tried using array_chunk or inserting if condition split different columns doesn't work. current code.

 $data['categories'] = array();          $categories_1 = $this->model_catalog_category->getcategories(0);          foreach ($categories_1 $category_1) {             $level_2_data = array();              $categories_2 = $this->model_catalog_category->getcategories($category_1['category_id']);              foreach ($categories_2 $category_2) {                 $level_3_data = array();                  $categories_3 = $this->model_catalog_category->getcategories($category_2['category_id']);                  foreach ($categories_3 $category_3) {                     $level_3_data[] = array(                         'name' => $category_3['name'],                         'href' => $this->url->link('product/category', 'path=' . $category_1['category_id'] . '_' . $category_2['category_id'] . '_' . $category_3['category_id'])                     );                 }                  $level_2_data[] = array(                     'name'     => $category_2['name'],                     'children' => $level_3_data,                     'href'     => $this->url->link('product/category', 'path=' . $category_1['category_id'] . '_' . $category_2['category_id'])                 );             }              $data['categories'][] = array(                 'name'     => $category_1['name'],                 'children' => $level_2_data,                 'href'     => $this->url->link('product/category', 'path=' . $category_1['category_id'])             );         } 

solved using css multi column property:

column-count column-gap column-rule-style column-rule-width column-rule-color column-rule column-span column-width

although not grid, job in dividing 1 column multiple columns. not ideal solution doing job.
