an easy task,
you can visit this page [url removed, login to view]
when you click the right bottom buttom, the dialog panle will disappear on web page.
and I need you do these 2 things:
1. make a similar effect with backbone, not with the exist intercom js.
[url removed, login to view] a chat room on the dialog panel, you can use the exist one I will provide to you later,
I have worked on ember js and backbone in multiple projects. I am familiar with its structure and also the handlebars. You will be satisfied with my work.
