ACF uses field groups to attach fields to posts. Each field group contains a title, fields, location rules and visual settings. To create a field group, click on the
Custom Fields menu item. You will see a welcome screen like this:
Clicking the “Add New” button will create a new Field Group. When editing a field group, you will see 3 areas of interest; Fields, Location and Options.
Each field group requires a title. This title is shown in the metabox handle on the edit screen. A good tip is to use relevant titles such as “Home Page” or “Event”
Here you can create and manage a variety of custom fields. Clicking the “Add Field” button will create a new field and add it to the bottom of the list (you can reorder your fields by dragging the order number as a handle). Adding a field will look like this:

Please note that location rules can be grouped together to create any combination of
For each field group, there are a few simple options to help customize the edit screen where this field group appears. If you have multiple field groups appearing on a page, the first field group’s options will be used. This is why you can set a order number. Field groups are loaded and displayed in order of their “order no” where 0 is the first and 99 is the last.
