Hi, I’m very new to Dash and Plotly and I encounter a problem using the dbc.Col/dbc.row tool.

I want to put two dropdowns side by side but my code stacked them one on the other and I don’t know why…

Here’s the code and result

If anyone have an idea of what I could’ve done wrong…

Hi @robertdinero and welcome to the Dash community 🙂

Try adding the Bootstrap stylesheet:

```auto
app = JupyterDash( __name__ , external_stylesheets=[dbc.themes.BOOTSTRAP])
```
