Our page-builder tools allow you to swap in alternate field value lists or update fields with specific values dynamically. In order to set up this dynamic behavior, you will need to first edit the form block.
You cannot use field updates with one-click pages.

In the IF row you will choose the form field that triggers your condition and the condition to check for (I.E. Is equal to, Contains, etc.).
The THEN row will let you swap in a different list of values or set a specific value.
Please note that you are limited to 15 field updates on any one Form Block.
Swapping Lists
Choosing “Swap List” will allow you to select the supporter field you want to change the content of and the list to populate that field with.

The values must be ~ separated by label and value. Excel is a handy tool for this.
