Recently, I was charged with integrating zopim with musicxray.com in an effort to improve our customer support experience. I must say, the software is really nice and functions about as good as I could have hoped for.
That said, if you have a design that does not allow for an ever present chat widget located in one of the four corners of you site, then you will have to use the zopim api and implement your own button.
Notice the button on the right side of the page. It fits with the theme of the site and is in a location of our choosing with an icon of our choosing. The html markup to achieve this button on our site is something like the following.
important: for this to work, you need to make sure that your zopim widget is hidden by default, you can do so using the zopim widget configuration interface
If you found this little snipped helpful or harmful then please leave a comment so we can discuss thins further.
