If you have a webpage within an HTML widget, and you click a link within that Widget, the webpage will open within that same frame.
To fix this, change your links in your widget to use the _parent
attribute for the target property.
<a href="http://site.com" target="_parent">Link to my site</a>
The other options for the ‘target’ attribute are below:
_blank
Opens the linked document in a new window or tab
_self
Opens the linked document in the same frame as it was clicked (this is default)
_parent
Opens the linked document in the parent frame
_top
Opens the linked document in the full body of the window
_framename
_ Opens the linked document in a named frame.
