+# InlineField
+
+A basic component for rendering form elements, like `Input`, `Select`, `Checkbox`, etc, inline together with `InlineLabel`. If the child element has `id` specified, the label's `htmlFor` attribute, pointing to the id, will be added.
+The width of the `InlineLabel` can be modified via `labelWidth` prop. If `tooltip` prop is provided, an info icon with supplied tooltip content will be rendered inside the label.
+
+# Usage
+
+```jsx
+<InlineField label="Inline field">
+  <Input placeholder="Inline input" />
+</InlineField>
+```

+<Props of={InlineField} />

+# InlineLabel
+
+A horizontal variant of `Label`, primarily used in query editors. Can be combined with form components that expect a label, eg. `Input`, `Select`, `Checkbox`.
+If you need to add additional explanation, use the tooltip prop, which will render an info icon with tooltip inside the label.
+For query editor readability, the label text should be as short as possible (4 words or fewer).
