Hi cw808,
I suggest you use the format below.
1. The red part is the actual value which will add for your select text in editor.
2. The orange part is the text which shows in the editor dropdown list
3. The blue part is the text (the text of #2 above) style which shows in the editor dropdown list
<item text="" value="20pt">
<html><![CDATA[<font style='color:red'>size 8</font>]]></html>
</item>
Regards,
Ken
