[Design] Redesign skip logic UI (hide/show questions)

[nichole-aquino]

Overview

Form builders can easily add hide/show logic within the edit component screen.

Context

Reference:

• Eng ticket: Implement skip logic (hiding/showing questions based on previous answers) #367
• Figma
• Prototype
• USWDS: modal

Revisit the logic UI to address the following issues:

• With the addition of the optional help text and information box, the overall height of the edit screen increases, making it cumbersome for builders to set logic. With the UI proposed here, builders must add a rule at the bottom, scroll up to the preview to read instructions, then scroll back down to set the action.
• The accordion to unfurl the hide/show logic can be mistaken for the accordion of the information box.

Solution:

• Simplify this experience by allowing builders to add logic within the question/answer option UI
• To add a rule: Click 'Add rule' next to either answer option to open a modal. Set the rule(s) and save.

• To edit a rule: Click the link to the right of the answer option to open the modal, where you can edit the rule.
  

• Example of an answer option that takes up 2 lines (middle align with dropdown)
  

Acceptance Criteria

The changes should be made to the following question types:

• Single select (aka radio buttons)
• Checkbox
• [Out of scope for MVP] Components with a number field (e.g. date or zipcode)
