I have an input text field, and a dynamic text field, so i typed something on my input text field and the text shows on the dynamic, this is ok.

But what i need is, once you typed the text, you can have 3 options to change the font (Arial, Tahoma or Times) pressing a button (one button per each font) so once you click on the desired font, it will change on the dynamic field.

How can i do this?

Thank
Gian
