# TabsDynamic

## Introduction

**`TabsDynamic`** is a versatile widget in Supervisely that allows users to display and edit YAML files within their info, such as NN model settings. The widget can divide the YAML file into separate tabs, making it easier to navigate and manage complex data structures. Additionally, users can edit the YAML directly within the widget and obtain a merged YAML file with their changes. `TabsDynamic` also enables users to get or set the active tab from code.

## Function signature

```python
TabsDynamic(
    filepath_or_raw_yaml,
    type="border-card",
    disabled=False,
    widget_id=None,
)
```

## Mini App Example

You can find this example in our Github repository:

[ui-widgets-demos/layouts and containers/013\_tabs\_dynamic/src/main.py](https://github.com/supervisely-ecosystem/ui-widgets-demos/blob/master/layouts%20and%20containers/013_tabs_dynamic/src/main.py)

### Import libraries

```python
import os

import supervisely as sly
from dotenv import load_dotenv
from supervisely.app.widgets import Card, Container, TabsDynamic
```

### Init API client

First, we load environment variables with credentials and init API for communicating with Supervisely Instance:

```python
load_dotenv("local.env")
load_dotenv(os.path.expanduser("~/supervisely.env"))

api = sly.Api()
```

### Initialize `TabsDynamic` widget

```python
yaml_path = "layouts and containers/013_tabs_dynamic/yaml/file_1.yaml"
tabs_dynamic = TabsDynamic(yaml_path)
```

### Create app layout

Prepare a layout for app using `Card` widget with the `content` parameter and place widget that we've just created in the `Container` widget.

```python
card = Card(title="TabsDynamic", content=Container([tabs_dynamic]))
layout = Container(widgets=[card])
```

### Create app using layout

Create an app object with layout parameter.

```python
app = sly.Application(layout=layout)
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://developer.supervisely.com/app-development/widgets/layouts-and-containers/tabsdynamic.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
