# SelectProject

## Introduction

**`SelectProject`** widget in Supervisely is a dropdown menu that allows users to select a project from a list of available projects in current workspace. Clicking on it can be processed from python code. This widget is particularly useful when working with multiple projects in Supervisely and allows to easily switch between projects in applications.

## Function signature

```python
SelectProject(
    default_id=None,
    workspace_id=None,
    compact=False,
    allowed_types=[],
    show_label=True,
    size=None,
    widget_id=None,
)
```

## Mini App Example

You can find this example in our Github repository:

[ui-widgets-demos/selection/004\_select\_project/src/main.py](https://github.com/supervisely-ecosystem/ui-widgets-demos/blob/master/selection/004_select_project/src/main.py)

### Import libraries

```python
import os

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

### 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()
```

### Prepare `project_id` and `workspace_id`

```python
workspace_id = sly.env.workspace_id()
project_id = sly.env.project_id()
```

### Initialize `SelectProject` widget

```python
select_project = SelectProject(
    default_id=project_id,
    workspace_id=workspace_id,
)
```

### 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="Select Project",
    content=Container(widgets=[select_project]),
)

layout = Container(widgets=[card])
```

### Create app using layout

Create an app object with layout parameter.

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