# Custom toolbar demo

If you don’t want to or can’t use the built-in toolbar, you can implement your own. This demo application shows you how.

[Try demo](https://www.docuvieware-demo.com/custom_toolbar_demo.aspx)

In this demo application, the default toolbar is disabled and a new one with minimal features is implemented, similar to what can be found in a web browser PDF viewer.

If no document is loaded in DocuVieware, the toolbar appears to let you load one. Once a document is loaded, you can make the toolbar appear by hovering over the bottom part of the viewer.
