Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Set condition to 'state=2' and add a script action that sets the field's visible attribute based on the checkbox value
UI Policies have both a condition and actions. The script action can evaluate additional conditions. The best practice is to set the condition to the primary filter (state=2) and add a script action to set the field's visibility based on the checkbox. Option A describes that correctly.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Set condition to 'state=2' and add a script action that sets the field's visible attribute based on the checkbox value
Why this is correct
Correct; the condition runs on server, and the script runs client-side to react to checkbox changes.
- ✗
Add both conditions in the condition builder: checkbox=true AND state=2
Why it's wrong here
Incorrect; UI Policy conditions are evaluated on the server before the form loads, so dynamic client-side changes like checkbox state are not available in the condition.
- ✗
Set condition to 'state=2' and add a reverse if false action with a condition on the checkbox
Why it's wrong here
Incorrect; reverse if false does not evaluate client-side conditions.
- ✗
Use a Client Script instead of UI Policy
Why it's wrong here
Incorrect; client scripts can do the same, but the question asks for UI Policy approach.
