GravityView needs to:

• [ ] Support the option to choose what to display, choice, value, or image (for image choices) on the field options modal for both fields.
• [ ] Multiple Choice - Select One (radio) doesn't show the selected choice when editing (but allows it to be edited)
• [ ] Image Choice - Select One (radio) doesn't show the selected choice when editing (but allows it to be edited)
• [ ] Search Bar needs to support searching for these as similar to radio/checkbox/select (only text at this moment)
• [x] Supported on Advanced Filters/Query Filters
