How do we edit this?

Can you post a link to your website? Thanks.

Could anyone tell me?

Try to use this one.

#wpdm-pf .col-md-8,
#wpdm-pf .col-md-4{width: 100% !important;}

Hope it works.

Thanks a lot, it worked !

One more thing, how to get only ‘Create a New Package’..i dont want other 3 tabs from displaying.

I think it will work for all the form with id wpdm-pf where col-md-8 and col-md-4 will be affected. And the create new package is the same as the form with id wpdm-pf.
