You can choose either a Room Mockup or a Personal Space, (or both) to use on your widget buttons. 

To use a Room Mockup: 

  1. Log into your dashboard 
  2. Head to the Widget tab and choose Sample Room widget
  3. Type in the name of the Room Mockup you liked

To use a Personal Space:

  1. Follow the same steps, but on step 3. type in any random space name. 
  2. On your final code, you will see the space attribute and the id of the space you chose. This has to be replaced with the id of your own space, which you will find on the search bar URL when clicking on your space.
