I am trying to search for help, however, because I do not know the name of the field, it is hard to search. I would like to add a field type that allows the user to add more fields. For example, I am collecting various social media accounts for golf courses. Some have facebook, some have twitter, some have even more. I would like to add a button that when clicked it adds one row. In that row, it should be a drop down of social media accounts and on the right an input box… at at least something like that. What is this called and is it available in ACF?
You have multiple ways according to what you want to do.
The most likely will probably be “Repeater Fields” from the Pro version.
Content Flexible can work too depending your mindset.
