How to increase the width of sur name field?

hi

I'm using the Name field so that I've a prefix, first and surname. How do I extend the number of characters that can be included in the surname field? the option doesn't appear to be available in the advance field.

thank you

I am not sure I understood your question correctly. There is no limit on the number of characters that you can enter.

To clarify, you wish to increase the width of the Last Name textbox to see the whole text when the name contains more characters?

If yes, please add the CSS code below:

#last_3{

  width: 180px;

}

Feel free to change the width as per your wish.
