This article demonstrates how to hide the Size field (shown below) on a layout and replace it with a different field. A rule populates the value from the new field into the hidden field.

Role required: Admin
Procedimento
-
In the layout wizard, turn off the Show Size Field setting.
Although the set size field still exists, it no longer appears in the layout. For more information about sets and layouts, see Using sets in layouts.
-
Create your replacement number field and add it to the layout.
You can change the display type as desired. In the example below, we created a number field using a slider.
The final task is to create a rule to take the value from the new field and enter it into the (hidden) Size field.
-
Create a rule, set your conditions, and create a Determination Action.
In the rule action:
- Define your original Set Size field as the field in which the value will be injected.
- Select Advanced.
- Click Edit Advanced Function and input a single line of code that returns the value of your new field.
For example, assume that the new field has a value of numberOfHardDrives. As seen in the image below, our line of code would simply be:
return cfg.numberOfHardDrives;
