We have just published an awesome plugin that will let you create beautiful custom designed drop down lists. Use one of the built-in themes, or configure custom design. Some of the parameters include - background and font colours, border width, indents, rounding, arrow size. Total over 20 parameters to let you create your very own perfectly designed dropdown list. You can even open or close drop down list from a workflow!
