Unable to fetch the menu sub-menu

[waqaspuri]

I'm unable to fetch the records from the following sitemap

{"_id":"new","startUrl":["https://www.arshadbrothers.com.pk/"],"selectors":[{"id":"main-category","parentSelectors":["_root"],"type":"SelectorLink","selector":"a.dropdown-item.dropdown-toggle","multiple":true,"linkType":"linkFromHref"},{"id":"sub-menu","parentSelectors":["main-category"],"type":"SelectorLink","selector":"li:nth-of-type(1) li a","multiple":true,"linkType":"linkFromHref"}]}

it fetching "Industrial Gloves" Menu.

{"_id":"new","startUrl":["https://www.arshadbrothers.com.pk/"],"selectors":[{"id":"sub-menu","parentSelectors":["category"],"type":"SelectorLink","selector":"ul a.dropdown-item","multiple":true,"linkType":"linkFromHref"},{"id":"category","parentSelectors":["_root"],"type":"SelectorLink","selector":"a.dropdown-item[href*=\"#\"]","multiple":true,"linkType":"linkFromHref"}]}

it works! but could you please let me know what is the good way to determine the selectors or a Chrome Extension that can help to get the Selectors for Web Scraper easily.
