Is it possible to limit the Excerpt field on the post page in words? Note that I am aware that it's possible to echo the excerpt and limit it in words, but I want the field itself to limit the amount of words, similar to how character limits on text-areas work.
Is such thing possible? Maybe a Javascript solution? Maybe something similar to what this plugin does to the character bio field (although its limitation is based on amount of characters).
The reason of this is that I run a multiple author platform where users often make the mistake to exceed the word limit that is being printed in the list of posts.
