Thank you for your suggestions.
Unfortunately, they don't seem to answer my question.
I have a dropdown in the toolbar that needs to be populated by the database.
On submitting the contents of the editor to the database, I also need to submit the selected value of the dropdown to the database.
The dropdown does not enter anything into the editor textarea.
Rather than giving the button example so that we can try to work out how to adapt it to what we want, could I ask/suggest that your company make a simple dropdown example. There seems to be the demand for it on this forum. There are a lot of questions about dropdowns and it does not seem to be possible to get this information from the documentation.
Thank you.
