Configuring elements on the canvas
Certain elements, mainly those with more complex behaviour like maps, tabs, contact forms, device mockups, etc. come with custom configuration menus allowing you to configure and customise the element.
To access the element configuration menu, select the item on the canvas and click once to bring up the sidebar to the right of the screen. If the element has a configuration menu available, you'll see two tabs towards the top of the sidebar:
Click the second tab, labeled "Functionality" to switch from the style editor to the element configuration menu. Depending on what element you have selected on the canvas, you'll see different configuration options (each element has it's own, specific configuration options).
