Creates multiple sidebars.
If you wanted to quickly create multiple sidebars for a theme or internally. This function will allow you to do so. If you don’t pass the ‘name’ and/or ‘id’ in $args, then they will be built for you.
(int) (Optional) Number of sidebars to create.
Default value: 1
(array|string) (Optional) Array or string of arguments for building a sidebar.
(string) The base string of the unique identifier for each sidebar. If provided, and multiple sidebars are being defined, the ID will have "-2" appended, and so on. Default 'sidebar-' followed by the number the sidebar creation is currently at.
(string) The name or title for the sidebars displayed in the admin dashboard. If registering more than one sidebar, include '%d' in the string as a placeholder for the uniquely assigned number for each sidebar. Default 'Sidebar' for the first sidebar, otherwise 'Sidebar %d'.
Default value: array()
