Components

Pickers — rich popups with full interaction

Calendar popups, scrolling time panels, range selection with hover highlighting — everything you'd expect from a production date/time picker.

Inputs — simple keyboard-only entry

Lightweight alternatives with no popup. Users navigate date segments with arrow keys and typing.

Selection

Tree — hierarchical data selection

Display & Input

All components are MIT licensed (RSuite is fully open-source).

Requirements

• Streamlit >= 1.51: these components are built on Streamlit Components v2; 1.51 is the first release with the st.components.v2 API they rely on. st-rsuite works on every release from 1.51 onward (on 1.51 and 1.52 a small compatibility shim applies isolate_styles on the per-call renderer; from 1.53 it is applied at registration). On older Streamlit the components cannot register and you get a must be declared ... with asset_dir error (see Troubleshooting).
• Python >= 3.10

Installation

uv add st-rsuite

or with pip:

pip install st-rsuite

Restricting selectable dates

date_picker and date_range_picker accept declarative constraints (the keyboard-only date_input / date_range_input do not, as RSuite has no calendar to disable). Callables can't cross the Python/JS boundary, so pass plain values and the frontend builds the shouldDisableDate predicate for you:

from datetime import date
from st_rsuite import date_picker

# Only weekdays in a fixed window, with a couple of holidays blocked out.
picked = date_picker(
    label="Appointment",
    min_date=date(2026, 6, 1),
    max_date=date(2026, 6, 30),
    disabled_dates=[date(2026, 6, 19)],   # individual dates
    disabled_weekdays=[5, 6],             # 0=Monday .. 6=Sunday, so Sat/Sun
    key="appt",
)

min_date / max_date are inclusive. disabled_weekdays uses the same numbering as Python's date.weekday() (Monday is 0). limit_start_year / limit_end_year bound the years reachable in the calendar, relative to the current selection.

Shortcut ranges

date_range_picker shows shortcut presets beside the calendar. It ships RSuite's defaults (Today, Yesterday, Last 7 days); pass your own with ranges, or ranges=[] to hide the sidebar entirely.

from datetime import date, timedelta
from st_rsuite import date_range_picker

today = date.today()
start, end = date_range_picker(
    label="Report window",
    ranges=[
        {"label": "Last 7 days", "value": (today - timedelta(days=6), today)},
        {"label": "Last 30 days", "value": (today - timedelta(days=29), today)},
        {"label": "This month", "value": (today.replace(day=1), today)},
    ],
    key="report",
)

Each preset is {"label": str, "value": (start, end)}, with optional "close_overlay": True (commit and close on click) and "placement": "bottom" | "left".

Inputs

Simple keyboard-only components — no popups, designed for compact quick-entry scenarios.

date_input

date_input(
    label="",
    value=None,           # date object or YYYY-MM-DD string
    format="yyyy-MM-dd",
    size="md",
    placeholder=None,
    disabled=False,
    locale=None,
    on_change=None,
    key=None,
) -> date | None

date_range_input

date_range_input(
    label="",
    value=None,           # tuple of (date, date) or (str, str)
    format="yyyy-MM-dd",
    character=" ~ ",      # separator between start and end
    size="md",
    placeholder=None,
    disabled=False,
    locale=None,
    on_change=None,
    key=None,

Selection

radio_tile

radio_tile(
    options=[...],        # list of dicts: {value, label, description?, icon?}
    value=None,           # default selected value
    inline=False,         # horizontal layout
    disabled=False,
    locale=None,
    on_change=None,
    key=None,
) -> str | None

select_picker

select_picker(
    items=[...],          # list of dicts: {value, label, group?}
    value=None,           # default selected value
    label="",             # label above the control
    searchable=True,      # show search input in the dropdown
    virtualized=False,    # virtualize very large lists
    disabled_items=None,  # values rendered non-selectable
    appearance="default", # 'default' | 'subtle'
    size="md",            # 'lg' | 'md' | 'sm' | 'xs'
    placeholder="Select",
    placement="bottomStart",
    disabled=False,
    cleanable=True,
    block=False,

    help=None,            # tooltip next to the label
    locale=None,
    on_change=None,
    key=None,
) -> str | None

Options group automatically under headings when any item carries a group key.

tag_picker

tag_picker(
    items=[...],          # list of dicts: {value, label, group?}
    value=None,           # list of selected values
    label="",
    searchable=True,
    virtualized=False,
    creatable=False,      # let users create options not in items
    disabled_items=None,
    size="md",
    placeholder="Select",
    placement="bottomStart",
    disabled=False,
    cleanable=True,
    block=False,
    loading=False,
    help=None,
    locale=None,
    on_change=None,
    key=None,
) -> list[str]

Multi-select rendered as removable tags. With creatable=True, values the user types that are not in items become selectable options and come back in the return list.

    value=None,           # single selected value
    label="",             # label above the control
    searchable=True,
    virtualized=False,    # virtualize very large trees
    default_expand_all=False,
    show_indent_line=False,
    only_leaf_selectable=False,  # keep branch nodes unselectable
    disabled_items=None,  # values rendered non-selectable
    height=320,           # tree height in px inside the dropdown
    appearance="default",

Single-select counterpart of check_tree_picker.

cascader

cascader(
    data=[...],           # [{value, label, children?: [...]}]
    value=None,           # single selected value
    label="",
    parent_selectable=False,  # allow non-leaf nodes as the answer
    searchable=True,
    disabled_items=None,
    column_width=156,     # width of each cascade column
    column_height=320,    # height of each cascade column
    appearance="default",

    block=False,
    loading=False,
    help=None,
    locale=None,
    on_change=None,
    key=None,
) -> str | None

Single-select counterpart of multi_cascade_tree. By default only leaf nodes are selectable; set parent_selectable=True to accept any level.

multi_cascade_tree

multi_cascade_tree(
    data=[...],           # [{value, label, children?: [...]}]
    value=None,           # list of selected values
    cascade=True,
    searchable=False,

Display & Input

carousel

carousel(
    items=[...],          # [{content?, src?, alt?, background?, color?}]  # src: URL or local file path
    autoplay=True,
    autoplay_interval=4000,  # ms between slides
    placement="bottom",   # indicator: 'top' | 'bottom' | 'left' | 'right'
    shape="dot",          # indicator: 'dot' | 'bar'
    active_index=0,
    locale=None,
    on_change=None,
    key=None,
) -> int                  # active slide index

A non-URL src is read from the local filesystem and inlined as a base64 data URI, so it must be a trusted path chosen by the app, not unsanitized user input.

timeline

timeline(
    items=[...],          # [{content, time?, icon?, color?}]
    align="left",         # 'left' | 'right' | 'alternate'
    endless=False,        # continuous timeline line
    locale=None,
    key=None,
) -> None                 # display-only

The icon field accepts react-icons names (e.g. "FaCheck", "FaTruck", "MdEmail") or emoji strings as fallback. 150+ icons from Font Awesome 5 and Material Design are included.

pin_input

pin_input(
    length=6,
    value="",
    mask=False,           # password-style masking
    type="number",        # 'number' | 'alphabetic' | 'alphanumeric'
    size="md",
    placeholder="",
    disabled=False,
    read_only=False,
    otp=False,            # one-time password autocomplete
    attached=False,       # remove spacing between fields
    locale=None,
    on_change=None,
    key=None,
) -> str                  # current PIN value

Locale / i18n

All components accept a locale parameter to switch calendar labels, month/day names, and button text to the target language. RSuite ships 29 locales out of the box.

When locale is not set, the component automatically detects the browser's language (navigator.language) and uses the closest matching RSuite locale.

from st_rsuite import date_picker

# Japanese
date_picker(label="日付を選択", locale="ja_JP", one_tap=True, key="jp")

# Chinese (Simplified)
date_picker(label="选择日期", locale="zh_CN", one_tap=True, key="cn")

# Spanish
date_picker(label="Elegir fecha", locale="es_ES", one_tap=True, key="es")

Available locales: ar_EG, ca_ES, cs_CZ, da_DK, de_DE, en_GB, en_US, es_AR, es_ES, fa_IR, fi_FI, fr_FR, gu_IN, hu_HU, it_IT, ja_JP, kk_KZ, ko_KR, ne_NP, nl_NL, pl_PL, pt_BR, ru_RU, sv_SE, th_TH, tr_TR, uk_UA, zh_CN, zh_TW

Locales load lazily: a page downloads only the locale it actually renders (a few KB), never the whole set.

Running the example

uv add st-rsuite
uv run streamlit run examples/showcase.py

Development

# Clone and install
git clone https://github.com/lperezmo/st-rsuite.git
cd st-rsuite
uv sync --dev

# Build frontend
cd st_rsuite/frontend
npm install
npm run build
cd ../..

# Run showcase
uv run streamlit run examples/showcase.py

Troubleshooting

streamlit.errors.StreamlitAPIException: Component 'st-rsuite.rsuite' must be declared in pyproject.toml with asset_dir to use file-backed js

Streamlit could not find st-rsuite's bundled frontend assets when it started. Check two things:

1. Streamlit version. st-rsuite needs Streamlit >= 1.51 (the first release with the st.components.v2 API). Upgrade and fully restart the app:

   uv add "streamlit>=1.51"      # or: pip install -U "streamlit>=1.51"
   

2. st-rsuite install. Make sure the package is current and installed from its wheel, which ships the built assets: uv add -U st-rsuite (or pip install -U st-rsuite), then restart the app.

Disclaimer

Full disclaimer: This project was built with the help of Claude Opus 4.6 by Anthropic, using Claude Code and streamlit/agent-skills. It is heavily based on st-mui.
