Examples

Example 1: Create a selct box with static values

Goal: Create a selectBox with static values.

Use the values field to list possible values.

{
  "type": "selectBox",
  "form": "quiz",
  "formDataKey": "favoriteColor",
  "font": "Raleway-Regular",
  "fontColor": "#F3F3F3",
  "fontSize": "16pt",
  "value": "select",
  "values": [
    {
      "value": "select",
      "display": "Select your favorite color!"
    },
    {
      "value": "#00F400",
      "display": "Green"
    },
    {

      "display": "Red"
    }
  ],
  "constraints": [
    {
      "type": "pos",
      "anchor": "c",
      "x": "50%",
      "y": "20%"
    },
    {
