JavaScript middleware is skipped during server-side prerendering. | | Markdown | `string?` | null | The Markdown string value to render as an html element. | | Middleware | `Func<string, Task<string>>?` | null | The C# function to run after parsing markdown and before rendering HTML. The middleware receives the parsed HTML string and returns the processed HTML string. C# middleware is applied after JavaScript middleware. | | NoPrerender | `bool` | false | Disables parse and render of the markdown content in the prerendering phase. | | OnParsing | `EventCallback<string?>` | null | A callback that is called before starting to parse the markdown. | | OnParsed | `EventCallback<string?>` | null | A callback that is called after parsing the markdown. | | OnRendered | `EventCallback<string?>` | null | A callback that is called after rendering the parsed markdown. | | AriaLabel | `string?` | null | Gets or sets the accessible label for the component, used by assistive technologies. | | Class | `string?` | null | Gets or sets the CSS class name(s) to apply to the rendered element. | | Dir | `BitDir?` | null | Gets or sets the text directionality for the component's content. | | HtmlAttributes | `Dictionary<string, object>` | new Dictionary<string, object>() | Captures additional HTML attributes to be applied to the rendered element, in addition to the component's parameters. | | Id | `string?` | null | Gets or sets the unique identifier for the component's root element. | | IsEnabled | `bool` | true | Gets or sets a value indicating whether the component is enabled and can respond to user interaction. | | Style | `string?` | null | Gets or sets the CSS style string to apply to the rendered element. | | TabIndex | `string?` | null | Gets or sets the tab order index for the component when navigating with the keyboard. | | Visibility | `BitVisibility` | BitVisibility.Visible | Gets or sets the visibility state (visible, hidden, or collapsed) of the component. | ## Public Members | Name | Type | Default Value | Description | | :--- | :--- | :------------ | :---------- | | UniqueId | `Guid` | Guid.NewGuid() | Gets the readonly unique identifier for the component's root element, assigned when the component instance is constructed. | | RootElement | `ElementReference` | | Gets the reference to the root HTML element associated with this component. | ## Enums ### BitVisibility Enum | Name | Value | Description | | :--- | :--- | :---------- | | Visible | 0 | The content of the component is visible. | | Hidden | 1 | The content of the component is hidden, but the space it takes on the page remains (visibility:hidden). | | Collapsed | 2 | The component is hidden (display:none). | ### BitDir Enum | Name | Value | Description | | :--- | :--- | :---------- | | Ltr | 0 | Ltr (left to right) is to be used for languages that are written from the left to the right (like English). | | Rtl | 1 | Rtl (right to left) is to be used for languages that are written from the right to the left (like Arabic). | | Auto | 2 | Auto lets the user agent decide. It uses a basic algorithm as it parses the characters inside the element until it finds a character with a strong directionality, then applies that directionality to the whole element. | ## Examples \n**Basic**: ```razor ``` \n**Advanced**: ```razor ``` ```csharp private string advancedMarkdown = @"
