This would just be helpful in choosing from the existing fonts though. I doubt if you can add a new font type to the list. Since we base our RTE on 3rd party CKEditor, you could also check in with them on how to do this and whether they offer extension points to allow you to extend it for your needs.

Hi ,

You can use the below script in userWorkForm to fix the font name and font size 

<script>
window.customCKEditorFontSizes = '12/12px';

    window.customCKEditorFonts = "Helvetica"; 
                        
</script>

If you need more number of font sizes in the dropdown ,add the elements to the variable as below .

window.customCKEditorFontSizes = '8/8px;10/10px;13/13px;16/16px;24/24px;';

Please note that these changes will override the default values .

Tried 

<script>

window.customCKEditorFontSizes = '12/12px';

window.customCKEditorFonts = "Helvetica"; 

                        

</script>

The font dropdown was restricted to Helvetica only. But if user doesn't select the text and applies the font, then the font=helvetica markup doesn't get added. Which is a limitation I can live with.

Font didn't restrict the dropdown to 12px. It shows everything and if I select 8px it applied 8px markup.So, not working. Any thoughts ?
