Using Multiple Taxonomies in ACF Repeater

I was trying forever to get a good way to allow a user to select from multiple different taxonomies in one ACF drop down. I eventually realized that is just not possible.

Instead, what we need to do is use a select field and populate it dynamically.

To do this, simply create a select field in your ACF. I ended up doing this inside of a repeater, like so:

Now we just need to populate this select field to simulate our taxonomy field. Here is the code for that:

There we go! Now you have a select field that allows the user to select between two ( or more ) taxonomies!
