Sub menu width

How can I modify sub menu width?

I'm tried find CSS code, but it's applied directly, not in CSS file.

 

Put the following code in your custom css

Appearance -> theme options -> styling options -> custom css

Code:

#menu .ddsmoothmenu li ul li:last-child {
width: 80px;
}
#menu .ddsmoothmenu li ul li:last-child a {
width: 50px;
}

This will solve your problem.
