You can embed content on your board by using the embed feature in Collaboard. 

You can copy and paste the URL or the iFrame code here.


You get a new object on your board displaying the embedded content. The embed object is always displayed on top of all other elements.

Embed Transparency

By default embedded objects are semi-transparent and only when you click on the embedded object will it be without transparency. 

In the settings panel, you can disable the semi-transparency of embedded objects.
