How do I get all Choice items to render in a single line?

To display the choices in a single line, you can use the showInline="true" attribute within your <Choices> tag. This will render the choices horizontally instead of vertically. Here's how you can modify your existing <Choices> tag:

<Choices name="is_useful" toName="item" required="true" showInline="true">
  <Choice value="yes"/>
  <Choice value="no"/>
</Choices>

By adding showInline="true", the choices "yes" and "no" will be displayed in a single line, achieving the layout you're looking for.
