How to make the width:auto or width:100%?

[jitendravyas]

I'm making a responsive website where I need to change the size dropdown 4 times for 4 different screen sizes. I tried to increase and decrease the font size in dropdown but it's not working.

just add width: 100% to the theme file.

Do as Thermo says, but also set the autoWidth option to false in the call to dropkick: $('.elem').dropkick({autoWidth: false});
