in my site i have to display the dhtmlscheduler in div box,but in this html,body tags class there.this is the main problem(class) to display it in my site.
The scheduler can be placed inside any container on the page, just be sure that container has some non-zero width and height
( If you are using scheduler 1.x then container need to have position:relative )
If issue still occurs for you - please provide any kind of sample or demo link where it can be reconstructed.
( you can send such info directly to support@dhtmlx.com )
