Appending text within a drop down
I'm sure there's an easy way to do this, but I can't figure it out, perhaps because I'm pretty new to this all. Essentially, I'd like to create a drop down with various canned sentences, also editable, and I'd like to append the chosen sentences. That is, a user could pick sentence A, B and C and all would populate the associated box, rather than replacing as seems to be the default. Thanks!
