uiSchema Options for Semantic-UI

There are various options to pass to semantic theme fields.

Note that every semantic property within uiSchema can be rendered in one of two ways: {"ui:options": {semantic:{[property]: [value]}}}

In other words, the following uiSchema is equivalent:

Note: All fields have the following settings below as their default

fluid: Take on the size of its container.
inverted: Format to appear on dark backgrounds.
{
  "ui:options": {
    "semantic" : {
      "fluid": true,
      "inverted": false,
      "errorOptions": {
        "size": "small",
        "pointing": "above",
      }
    }
  }
}

Semantic Widget Optional Properties

errorOptions

The uiSchema semantic object accepts an errorOptions property for each field of the schema:

size: determines the size of the error message dialog
pointing: determines the direction of the arrow on the error message dialog

Below are the current defaults

const uiSchema = {
  "ui:options": {
    "semantic" : {
      "errorOptions": {
        "size": "small",
        "pointing": "above",
      }
    }
  }
};

semantic options uiSchema for array items

To specify a uiSchema that applies to array items, specify the semantic uiSchema value within the ui:options property:

wrapItem: wrap each array item in a Segment
horizontalButtons: horizontal buttons instead of the default vertical
const schema = {
  type: "array",
  items: {
    type: "string"
  }
};

const uiSchema = {
   "ui:options": {
      "semantic": {
        "wrapItem": true,
        "horizontalButtons": true
      }
    }
};

render((
  <Form schema={schema} uiSchema={uiSchema} />
), document.getElementById("app"));

formContext

The formContext semantic object accepts wrapContent ,wrapLabel properties.

wrapContent: wrap all inputs  field content in a div, for custom styling
wrapLabel: wrap all labels in a div, for custom styling via CSS
<Form
  formContext={{
    "semantic"={
      "wrapLabel": true,
      "wrapContent": true
    }
    uiSchema={uiSchema}
  // other props...
  }}
/>
