## Introduction
*The* quick **brown fox** jumps over the lazy dog. This is a simple quick example with various **formatting** elements.
### Lists and Items
Here are some important points:
1. **First item** - This is the primary consideration
2. *Second item* - Another important point
3. Third item with `inline code`
4. Fourth item containing [a link](https://example.com)

## `MarkdownLabel`
### Initialization
| name | type | default | description |
|---|---|---|---|
value |
```python dict | Callable | None ``` | None |
Dictionary containing markdown_content and highlights array. If a function is provided, the function will be called each time the app loads to set the initial value of this component. |
show_side_panel |
```python bool ``` | True |
Whether to show the detailed information side panel. |
panel_width |
```python str ``` | "300px" |
Width of the side panel (CSS value like "300px", "25%", etc.). |
edit_mode |
```python str ``` | "split" |
Layout for editing mode - "split" (side-by-side), "tabs", or "overlay". |
show_preview |
```python bool ``` | True |
Whether to show live preview in edit mode. |
markdown_editor |
```python str ``` | "textarea" |
Type of markdown editor - "textarea" or "codemirror" (future). |
label |
```python str | I18nData | None ``` | None |
the label for this component. Appears above the component and is also used as the header if there are a table of examples for this component. If None and used in a `gr.Interface`, the label will be the name of the parameter this component is assigned to. |
every |
```python Timer | float | None ``` | None |
Continously calls `value` to recalculate it if `value` is a function (has no effect otherwise). Can provide a Timer whose tick resets `value`, or a float that provides the regular interval for the reset Timer. |
inputs |
```python Component | Sequence[Component] | set[Component] | None ``` | None |
Components that are used as inputs to calculate `value` if `value` is a function (has no effect otherwise). `value` is recalculated any time the inputs change. |
show_label |
```python bool | None ``` | None |
if True, will display label. |
container |
```python bool ``` | True |
If True, will place the component in a container - providing some extra padding around the border. |
scale |
```python int | None ``` | None |
relative size compared to adjacent Components. For example if Components A and B are in a Row, and A has scale=2, and B has scale=1, A will be twice as wide as B. Should be an integer. scale applies in Rows, and to top-level Components in Blocks where fill_height=True. |
min_width |
```python int ``` | 160 |
minimum pixel width, will wrap if not sufficient screen space to satisfy this value. If a certain scale value results in this Component being narrower than min_width, the min_width parameter will be respected first. |
visible |
```python bool ``` | True |
If False, component will be hidden. |
elem_id |
```python str | None ``` | None |
An optional string that is assigned as the id of this component in the HTML DOM. Can be used for targeting CSS styles. |
elem_classes |
```python list[str] | str | None ``` | None |
An optional list of strings that are assigned as the classes of this component in the HTML DOM. Can be used for targeting CSS styles. |
render |
```python bool ``` | True |
If False, component will not render be rendered in the Blocks context. Should be used if the intention is to assign event listeners now but render the component later. |
key |
```python int | str | tuple[int | str, ...] | None ``` | None |
in a gr.render, Components with the same key across re-renders are treated as the same component, not a new component. Properties set in 'preserved_by_key' are not reset across a re-render. |
preserved_by_key |
```python list[str] | str | None ``` | "value" |
A list of parameters from this component's constructor. Inside a gr.render() function, if a component is re-rendered with the same key, these (and only these) parameters will be preserved in the UI (if they have been changed by the user or an event listener) instead of re-rendered based on the values provided during constructor. |
interactive |
```python bool | None ``` | None |
If True, the component will be editable allowing users to modify markdown content. |
rtl |
```python bool ``` | False |
If True, will display the text in right-to-left direction. |
