Working with site categories

Our CMS has features with the addition of categories. Let's look at them in more detail.If you are using a pure engine, without any plugins, then you don't have to do anything when creating categories. The created categories will be displayed when creating posts or news.In another case, when you install a plugin and want it to display the categories you need, you should in the "advanced" tab, in the "for plugins" section, select where this category will be displayed.If not selected, by default it will be displayed only when creating posts, news. If you select the desired plugin, it will be displayed only in it. Well, if you select -system-, it will also be displayed when creating posts.This is done for the optimization and usability of the CMS
