it is advantage of G2, not streamlit-g2.


:sparkles: Features

  • Progressive Usage - The main objective of G2 is to help you get meaningful visualizations quickly with concise declarations and it infers the rest. But you can configure much more for complex and advanced situations.
  • Declarative API - We employs a functional declarative API to specify chart options in a programmatic fashion, which contributes to better logic reuse and more flexible code organization.
  • High Extensibility - To satisfy specific needs, G2 provides a convenient and consistent mechanism to extend everything you can imagine, whether a scale, a transform, a mark, etc,. You can even customize a brand new visualization tool based on this mechanism.
  • Comprehensive Grammar - G2 rejects a chart typology in favor of marks, transforms, scales, coordinates, and compositions. In addition to static visual representations, it’s possible to declare data-driven animations and apply well-designed action-based interactions to plots as well.
  • Powerful Renderer - There is a powerful renderer G under G2 to generate web-based visualizations using Canvas, SVG or WebGL. The plenty of plugins it has benefit G2 from rendering charts with novel styles such as hand-drawn and fully embracing the ecosystem of D3.

Can you provide a snippet of the code? I seem to remember that there was a problem, but the details are not clear.
Btw,you can try the latest version 0.2.5.

Hello,
Great components! Thanks so much.
I have a question: how to retrieve a second consecutive click on a same button? The on_change only triggers if the last button was different … Setting index to None only hides it … This makes the group working as a radio group instead of buttons.
Is there a way to extend this rather than destroy and create a different group every single time (which is uncomfortable for both user and coder)?
Thanks a lot

Hi @ji_haoran

I am planning to duplicate the numeric keypad of the keyboard in my app. I created a 4x3 button matrix which works fine for desktop or mobile in landscape mode using vanilla streamlit. However, for mobile portrait mode, the 4x3 matrix changes to 1 column (i.e.1x12) using normal streamlit columns (with/out dummy padding columns). Streamlit can’t align buttons to the left like your widgets can.

Next, I already tried using 3 rows of sac.buttons but I can’t nullify the previous button selection in the common callback, as there can be only 1 button selected in all 3 rows.

Is the 4 columns x 3 rows matrix of number buttons possible by using just 1 set of sac.buttons (for the mobile portrait mode)?

Cheers

Hi all:
I want to check if it is possible to use the menu items build and if clicked, go to a page of a multi page app without rerunning and open the page in a new browser window?
At least that was the behaviour i saw when using the new site with href notation…
I was looking for switch_page() which is obviously not available here, since we don´t use the normal multi page approach.

all the best

Hello, I’d like to use this sac menu as an alternative sidebar menu for a multipage script, similar to what’s shown in the demo page

I see this example code:

import streamlit_antd_components as sac
sac.menu([
    sac.MenuItem('home', icon='house-fill', tag=[sac.Tag('Tag1', color='green'), sac.Tag('Tag2', 'red')]),
    sac.MenuItem('products', icon='box-fill', children=[
        sac.MenuItem('apple', icon='apple'),
        sac.MenuItem('other', icon='git', description='other items', children=[
            sac.MenuItem('google', icon='google', description='item description'),
            sac.MenuItem('gitlab', icon='gitlab'),
            sac.MenuItem('wechat', icon='wechat'),
        ]),
    ]),
    sac.MenuItem('disabled', disabled=True),
    sac.MenuItem(type='divider'),
    sac.MenuItem('link', type='group', children=[
        sac.MenuItem('antd-menu', icon='heart-fill', href='https://ant.design/components/menu#menu'),
        sac.MenuItem('bootstrap-icon', icon='bootstrap-fill', href='https://icons.getbootstrap.com/'),
    ]),
], open_all=True)

But I can’t find a way to make it work as an alternative sidebar!

Could you please show us the code of the sidebar inside https://nicedouble-streamlitantdcomponentsdemo-app-middmy.streamlit.app/ for example, or any another example of a working sidebar in order to use it as an alternative sidebar in a multipage?

antd sac menu is designed for a single file. You can put them in the sidebar this way:

main_page.py

with st.sidebar:
    menu_item = sac.menu([
        sac.MenuItem('home', icon='house-fill', tag=[sac.Tag('Tag1', color='green'), sac.Tag('Tag2', 'red')]),
        sac.MenuItem('products', icon='box-fill', children=[
            sac.MenuItem('apple', icon='apple'),
            sac.MenuItem('other', icon='git', description='other items', children=[
                sac.MenuItem('google', icon='google', description='item description'),
                sac.MenuItem('gitlab', icon='gitlab'),
                sac.MenuItem('wechat', icon='wechat'),
            ]),
        ]),
        sac.MenuItem('disabled', disabled=True),
        sac.MenuItem(type='divider'),
        sac.MenuItem('link', type='group', children=[
            sac.MenuItem('antd-menu', icon='heart-fill', href='https://ant.design/components/menu#menu'),
            sac.MenuItem('bootstrap-icon', icon='bootstrap-fill', href='https://icons.getbootstrap.com/'),
        ]),
    ], open_all=True)

Use the menu_item value to navigate in the main page.

Use the leaf/child and not the parent.

# python >= 3.10
match menu_item:
    case 'apple':
        st.write('apple page')

    case 'google':
        st.write('google page')
   ...

And to not mess up your existing pages display in the sidebar under pages folder for multi-page app, you can disable displaying them by modifying the config.toml.

.streamlit/config.toml

[client]
showSidebarNavigation = false

If you want to separate the pages by file, you can create a folder and put apple.py on it, where the contents of apple are all from apple.py. Create a folder named modules and some files such as apple.py, google.py, etc.

./modules/apple.py

import streamlit as st

def Apple():
    st.title('Welcome to apple page!!')

And modify your main_page.py.

main_page.py

from modules.apple import Apple

with st.sidebar:
    menu_item = sac.menu([ ...
...

match menu_item:
    case 'apple':
        Apple()
...

Or just use your existing pages/apple.py path.

from pages.apple import Apple

Or you can use the switch_page to navigate to the pages files.

match menu_item:
    case 'apple':
        st.switch_page('pages/apple.py')

However you will no longer see the sidebar menu because that sidebar menu is only shown for the main page.

Depending on your design you can explore different ways to show the sac menu, etc. I like the sac menu because of this multi-hierarchy and collapsibility.

Just great! Now I can use this custom navigation bar… but I still can see the original (default) one above (see image), because I use a multipage… can I hide the default navigation bar?
