I am working with WordPress theme customizer.
My client wants several options in customizer screen like site title, tagline and few other options. i had gone well with above options but i am getting confused how switch the themes in customizer
for example i am working on twenty fourteen, i have to show drop down options in customizer to change the theme preview to twenty thirteen, twenty twelve or all existing themes in that drop down. if the admin select the twenty twelve from drop down the customizer live preview has to be change to twenty twelve preview and once he press save & publish the website theme has to be change to twenty twelve.
anybody have idea how to add this option to WordPress customizer ...
