I have been hunting for a solution for 2 days. The Taxonomy field dropdown, displays the sub-category of the taxonomy with hyphen before. This makes the data entry very difficult, because, I have 1000’s of pre-entered choices in taxonomy and manually we are scrolling and choosing.
If the hyphen is removed, we could type the first few characters of the sub category and choose the required one.
Here is a screenshot
This must be a simple to fix for pro’s like you. But, it makes it very hard for me.
Can you please help me here? to fix this.
I’ve done some digging and there aren’t any filters that I can find that allow you do alter the label output.
You might try looking at http://www.advancedcustomfields.com/resources/acf-render_field/ and output the value of $field to see if you can alter it at that point, but that’s just a guess.
