如何使用dbc.行有效吗?

Question

我正在用dash-plotly构建一个应用程序，但我很困惑如何正确地图层项目。

import dash
import dash_bootstrap_components as dbc
from dash import html
from dash import dcc
app = dash.Dash(__name__)
app.layout = html.Div([
dbc.Row([ #row 1
dcc.Input(type='text'),
html.Button('A button'),
]),
html.Br(),
dbc.Row([ #row 2
dcc.Dropdown(['0','1', '2','3','4','5','6','7','8','9','10'],
'1',
style={
'width':'10%'}),
html.Button('A Button'),
])
])
if __name__ == '__main__':
app.run_server(debug=True)

行#1中的项是内联的，但行#2中的项是相互堆叠的。两行都由不同的元素组成，那么如何将行#2中的项强制为内联呢?关于dbc的规则是什么?行吗?

Answer 1

我认为这里的问题是，你正在使用短跑引导组件，但默认样式表，我认为你应该结合dbc.Col与dbc.Row，使更好的布局。下面是示例代码:

import dash
import dash_bootstrap_components as dbc
from dash import html
from dash import dcc
app = dash.Dash(__name__,external_stylesheets=[dbc.themes.LUX])
app.layout = html.Div([
dbc.Row([
dbc.Col([
dcc.Input(type='text')
],width={'size':1,'offset':0,'order':'1'}),
dbc.Col([
html.Button('A button'),
],width={'size':1,'offset':0,'order':'1'})
]),
html.Br(),
dbc.Row([
dbc.Col([
dcc.Dropdown(['0','1', '2','3','4','5','6','7','8','9','10'],
'1'),
],width={'size':1,'offset':0,'order':'1'}),
dbc.Col([
html.Button('A Button'),
],width={'size':1,'offset':0,'order':'1'})
])
])
if __name__ == '__main__':
app.run_server(debug=True)

如您所见，我在布局中添加了external_stylesheets=[dbc.themes.LUX]和dbc.Col。

你也可以使用Bootstrap 5代替dash Bootstrap组件库-

import dash
import dash_bootstrap_components as dbc
from dash import html
from dash import dcc
app = dash.Dash(__name__, external_stylesheets = ["https://cdn.jsdelivr.net/npm/bootstrap@5.0.2/dist/css/bootstrap.min.css"])
app.layout = html.Div([
html.Div([
html.Div(
dcc.Input(id = "input-1", type = "text", placeholder = "Enter", className = "form-control"),
className = "col-lg-5"),
html.Div(
html.Button("Submit", id = "submit-1", className = "btn btn-dark"),
className = "col-lg-3"),
], className = "row row-cols-auto mb-4"),
html.Div([
html.Div(
dcc.Dropdown(['0','1', '2','3','4','5','6','7','8','9','10'],
'1'),
className = "col-lg-5"),
html.Div(
html.Button("Submit", id = "submit-2", className = "btn btn-dark"),
className = "col-lg-3"),
], className = "row row-cols-auto")
], className = "container-fluid mt-2")
if __name__ == '__main__':
app.run_server(debug=True)[![Sample][1]][1]
