const cms = new TinaCMS();

cms.plugins.add(ConditionalFieldPlugin);
cms.plugins.add(ConditionalGroupFieldPlugin);

Making A Single Field Conditional

In a form config, you can use the condition field like any other field, providing it a child field to render when its condition returns true.

const fields = [
  { name: "type", label: "Type", component: "select", options: ["image", "Video"] }
  { 
    name: "image", 
    label: "Image", 
    component: "condition",
    condition: (value, values) => values.type === "image"
    field: { component: "image" }
  },
  { 
    name: "video", 
    label: "Video", 
    component: "condition",
    condition: (value, values) => values.type === "video"
    field: { component: "video" }
  }
]

Pro-tips

• The nested field will share the same name as the condition field if no name is specified for the nested field

Making Multiple Fields Conditional

In a form config, you can use the condition-group field like any other field, providing it a child fields to render when its condition returns true.

const fields = [
  { name: "type", label: "Type", component: "select", options: ["image", "Video"] }
  { 
    name: "image", 
    label: "Image Fields", 
    component: "condition-group",
    condition: (value, values) => values.type === "image"
    fields: [
      { name: "src", label: "Image", component: "image" },
      { name: "alt", label: "Alternative Text", description: "Displayed if the image fails to load and to screen readers", component: "image" }
    ]
  },
  { 
    name: "video", 
    label: "Video", 
    component: "condition-group",
    condition: (value, values) => values.type === "video"
    fields: [
      { name: "src", label: "Video", component: "video" },
      { name: "thumbnail", label: "Thumbnail Image", component: "image" }
    ]
  }
]

Pro-tips

• Unlike the condition field, the child fields of a condition-group must have their own name. However, the condition-group field does not require a name.
