A category is an organizational unit to which you assign your products. When viewing your store, customers will click on a category to view products that have been assigned to that category. You can also create subcategories within your category. Sometimes these categories are so many that you need to have a pagination for them also.
Following is how you can achieve that –
1.Upload <a href = “/wp-content/uploads/js” download> jquery.js </a> using webdav in your template files ex:/template/js/ quickpager.jquery.js.
2.Go to head.html and include the jquery file quickpager.jquery.js and add the below code before </head>.
NOTE: ul.side-menu is your subcategory ul tag class
