Yes, an example is on our home page www.setster.com and our features page www.setster.com/features where we have a button that calls up the overlay in the middle of the page.
Creating your own button
First you need to make sure you have the Setster code placed on your page. If you wish to not use the Setster button, then you need to select the “Hidden” option of the code and integrate it to your website first. This is done when getting the code from the Get Widget section under Settings. Instead of selecting left or right, select HIDDEN. Add the code to your page, above the following call. To get your code ready please see this FAQ.
Java Script Call: setster_widget.show();
The above will show the words "Book Appointment" and when clicked on this word the widget would open. This can also be done to an image
<a href=";" onclick="setster_widget.show(); return false;"><img src="..."></a>, or any object on your site.
