This portion represents an individual record. It has title, default, published, ordering, actions for a category. Category title is text how the category will appear in combo box or as value on (views and listings). Default means category will be selected by default (on page load) on forms. Publish status controls whether category will be visible in a combo box or not. Ordering means what will be the sequence of the categories in a combo box. Published, unpublished, default, ordering for user or visitor can be changed by a single click for all categories except certain categories. Ordering of any categories can be increased or decreased by a single click. If admin clicks on edit icon then admin will be redirected to add category layout with details of category filled in the form(edit case). If admin clicks on delete icon then category will be deleted, if no entity (company, job, resume) holds that category as value and it does not default category.
Unpublished category cannot be set default and also default category cannot be unpublished.
This is how a a subcategory is gonna appear, the difference between a category and sub category is subcategory title will have '|--' as prefix. Subcategory if a subcategory will have this prefix (|--) twice and so on.
