# ACF

It is not mandatory to have it installed; you can replace it with another option (e.g., Metabox). However, doing so will result in the loss of some dynamic layouts that rely on these custom fields.

The areas affected by ACF include:

* **Pages**: Description field + topbar section
* **Post category fields**: Category featured image + topbar section
* **Product category fields**: Category featured image, description + topbar section
