The downvote is probably because this question is not related to ACF.
That said, you should be able to achieve this with CSS columns - browser support is pretty good these days: http://caniuse.com/#feat=multicolumn
Hey just a sidenote, in your if statements above, the first statement will always return true. If you want to compare if two values are equal, you need to use a double or triple equals sign.
By only using one equals sign, you are essentially setting the value of the variable. If the variable isn't equal to false or zero, it will evaluate to true when in an if statement.
if ( $x == $y ) { // $x is equal to $y }
if ( $x = "some string" ) { // "some string" isn't false or 0 so it evaluates to true. }
You can read more about comparison operators in the PHP manual
Short answer: no.
Longer answer: nope.
WordPress is unique in that it gives developers an extremely extensible API to work with and build upon. With so many other CMS's, you have to do a lot of the legwork yourself.
That said, the closest thing I can think of is probably October CMS. Here's a link to some documentation regarding their backend form fields.
https://octobercms.com/docs/backend/forms
They have a repeater field type that can contain other fields, but it seems like it has some bugs (doesn't work with file uploads?). However, all of the logic to save that data needs to be written by you, the developer, albeit with some helper classes provided by October.
Drupal has something called Field Collections that I think is similar, but also requires a fair amount of code just to get it off the ground. Depending on how big your site is and how many custom content types you have, that could be a lot of manual code writing with some complicated syntax!
My 2¢, experiment with other CMSs for projects that are not centered around large amounts of text content. WordPress is so far ahead of these other platforms when it comes to publishing, you would be better off learning new techniques rather than adopting your WordPress ones.
Build a stats app or something with JS graphs, or a SoundCloud clone, etc.
And I say all this as the mod of this sub, with some bias and love for ACF :)
