Convert boolean field to custom style I have a Boolean field with Yes/No values with default style of Drupal . 



I want to change that field to ON and OFF toggle style like below . 



I understand that it can be done using the bootstrap theme and the bootstrap toggle module. But I don't need to change my theme. How can I do that ?
A quick look at the bootstrap toggle JavaScript code does not show any actual dependencies in it for the actual bootstrap theme.  You may be able to install the bootstrap_toggle module without the Bootstrap theme and it will work.

Won't hurt to try on a dev environment. :)
