Parent Topic: Device Type Definitions
Layout groups specify which property fields appear in a particular section of the user interface, as well as the section label.
You can define layout groups in-line, within a definition file for the user-interface element that contains the layout group. You can also define a layout group in a separate JSON file and call the file from the owning definition. This is useful for reusing the same layout group in multiple calling user-interface elements.
|Note This definition is one part within the device type definition structure. In other words, when you export and import a device type definition, this definition is included.|
Layout groups in JSON contain the following components:
|Orientation||The position that property fields listed in PropertyKeys appear relative to each other:
|HelpUrl||Creates a help button on the layout group that opens a window to a relative URL. For instance, a property value of help/helpTopic.html will open a new tab to http://serverHostname/help/helpTopic.html.|
