Dash Dynamic Grid Layout is a Dash component library that provides a flexible grid layout system for arranging and moving components within a Dash application.
Special thanks to BSd3v for contributing the improvements and bug fixes making this a much more polished project.
- Drag-and-drop functionality for rearranging components
- Resizable grid items
- Customizable layout with responsive breakpoints
- Option to add or remove items dynamically
- Customizable drag handles for each item
- Persistence of component state
- Local, memory, or session storage for persistence
pip install dash-dynamic-grid-layout
Here's a basic example of how to use the DashGridLayout component:
import dash_dynamic_grid_layout as dgl
from dash import Dash, html, dcc
import plotly.express as px
app = Dash(__name__)
df = px.data.iris()
app.layout = html.Div([
dgl.DashGridLayout(
id='grid-layout',
children=[
dgl.DraggableWrapper(
children=[
html.Div('Drag me!', style={'height': '100%', 'display': 'flex', 'alignItems': 'center', 'justifyContent': 'center', 'border': '1px solid #ddd', 'borderRadius': '5px'})
],
handleText='Move'
),
dgl.DraggableWrapper(
children=[
dcc.Graph(
figure=px.scatter(df, x="sepal_width", y="sepal_length", color="species"),
style={'height': '100%'}
)
],
handleText='Move Graph'
)
],
rowHeight=150,
cols={'lg': 12, 'md': 10, 'sm': 6, 'xs': 4, 'xxs': 2},
style={'height': '600px'},
)
])
if __name__ == '__main__':
app.run_server(debug=True)
