Can the Subcategories in This Website be Scraped?

https://guardian.com.my/index.php/default-menu.html

I have tried different ways but could not do it.
Can only scrape the categories on top navigation bar.

This is my sitemap:

{"_id":"guardian_all","startUrl":"https://guardian.com.my/index.php","selectors":[{"id":"item","type":"SelectorElement","selector":"li.item","parentSelectors":["pagination","category"],"multiple":true,"delay":""},{"id":"productname","type":"SelectorText","selector":"h2.product-name a","parentSelectors":["item"],"multiple":false,"regex":"","delay":""},{"id":"regular price","type":"SelectorText","selector":"span.regular-price span.price","parentSelectors":["item"],"multiple":false,"regex":"","delay":0},{"id":"oriprice","type":"SelectorText","selector":"p.old-price span.price","parentSelectors":["item"],"multiple":false,"regex":"","delay":""},{"id":"promoprice","type":"SelectorText","selector":"p.special-price span.price","parentSelectors":["item"],"multiple":false,"regex":"","delay":""},{"id":"minimal price","type":"SelectorText","selector":"p.minimal-price span.price","parentSelectors":["item"],"multiple":false,"regex":"","delay":0},{"id":"detailUrl","type":"SelectorLink","selector":"a.product-image","parentSelectors":["item"],"multiple":false,"delay":""},{"id":"pagination","type":"SelectorLink","selector":"div.category-products > div.toolbar li:nth-of-type(n+2) a","parentSelectors":["pagination","category"],"multiple":true,"delay":""},{"id":"thumbnail","type":"SelectorHTML","selector":"a.product-image","parentSelectors":["item"],"multiple":false,"regex":"","delay":""},{"id":"remark","type":"SelectorText","selector":"p.percentage-discount","parentSelectors":["item"],"multiple":false,"regex":"","delay":""},{"id":"category","type":"SelectorLink","selector":"li.menu-full-width:nth-of-type(n+2) > a","parentSelectors":["_root"],"multiple":true,"delay":0}]}
