In addition to applying a Floorplan on a Transaction, you can also apply a Floorplan on a Web Panel.
If you have never applied the Fiori pattern on your Knowledge Base, read GeneXus for SAP Fiori Mobile Pattern. Otherwise while being positioned on the Patterns tab of a Web Panel, click the Select floorplan... link:

It will open a new window with a list of floorplans to select one:

Once selected it will pop up a new window showing the four different options to base the floorplan on:
- Based on a Transaction
- This will create only the list using the attributes of the Transaction as columns.
- Based on a SDT
- This will create the list using the first level of the SDT as columns.
- Variables based on Attributes or Domains
- This will create the list using the variables as columns.
- Use custom variables
- This will create the list using the variables as columns.

After selecting one of these options, it will create only the list floorplan; you will need to create all the objects/code necessary to develop the logic of the Web Panel.
