The multiselect widget starts as empty. Parameters ---------- label: str A short label explaining to the user what this select widget is for. The label can optionally contain GitHub-flavored Markdown of the following types: Bold, Italics, Strikethroughs, Inline Code, Links, and Images. Images display like icons, with a max height equal to the font height. Unsupported Markdown elements are unwrapped so only their children (text contents) render. Display unsupported elements as literal characters by backslash-escaping them. E.g., ``"1\. Not an ordered list"``. See the ``body`` parameter of |st.markdown|_ for additional, supported Markdown directives. For accessibility reasons, you should never set an empty label, but you can hide it with ``label_visibility`` if needed. In the future, we may disallow empty labels by raising an exception. .. |st.markdown| replace:: ``st.markdown`` .. _st.markdown: https://docs.streamlit.io/develop/api-reference/text/st.markdown options: Iterable Labels for the select options in an ``Iterable``. This can be a ``list``, ``set``, or anything supported by ``st.dataframe``. If ``options`` is dataframe-like, the first column will be used. Each label will be cast to ``str`` internally by default. default: Iterable of V, V, or None List of default values. Can also be a single value. format_func: function Function to modify the display of the options. It receives the raw option as an argument and should output the label to be shown for that option. This has no impact on the return value of the command. key: str or int An optional string or integer to use as the unique key for the widget. If this is omitted, a key will be generated for the widget based on its content. No two widgets may have the same key. help: str or None A tooltip that gets displayed next to the widget label. Streamlit only displays the tooltip when ``label_visibility="visible"``. If this is ``None`` (default), no tooltip is displayed. The tooltip can optionally contain GitHub-flavored Markdown, including the Markdown directives described in the ``body`` parameter of ``st.markdown``. on_change: callable An optional callback invoked when this widget's value changes. args: tuple An optional tuple of args to pass to the callback. kwargs: dict An optional dict of kwargs to pass to the callback. max_selections: int The max selections that can be selected at a time. placeholder: str A string to display when no options are selected. Defaults to "Choose an option." disabled: bool An optional boolean that disables the multiselect widget if set to ``True``. The default is ``False``. label_visibility: "visible", "hidden", or "collapsed" The visibility of the label. The default is ``"visible"``. If this is ``"hidden"``, Streamlit displays an empty spacer instead of the label, which can help keep the widget alligned with other widgets. If this is ``"collapsed"``, Streamlit displays no label or spacer. Returns ------- list A list with the selected options Example ------- >>> import streamlit as st >>> >>> options = st.multiselect( ... "What are your favorite colors", ... ["Green", "Yellow", "Red", "Blue"], ... ["Yellow", "Red"], ... ) >>> >>> st.write("You selected:", options) .. output:: https://doc-multiselect.streamlit.app/ height: 420px )rWr'rDrZr\r^r`rbrdrKrTrUrVctx)r _multiselect)r.rWr'rDrZr\r^r`rbrdrKrTrUrVrgr0r0r1rRjs"zzMultiSelectMixin.multiselect)rKrTrUrVrgrErgScriptRunContext | Nonec  s^t|}d}t|j|||dt|| t|}fdd|D}t||}t|j}t|||||||| | d }t}||_ ||j dd<||_ | |_ ||_ | pQd|_| |_t| |j_||jdd<|durlt||_t||}t|j ||| |j|j|dd}t|j| t|||}|jr||j|jdd<d |_|rt|||j|||jS) NrRr<csg|]}|qSr0r0)r8optionrZr0r1r;sz1MultiSelectMixin._multiselect..)user_keyform_idrWr'rDr^rKrTrint_array_value)on_change_handlerrbrd deserializer serializerrg value_typeT) rrdgrrrr rMultiSelectProtoidrDrmrUrWrKrTrrVr+r'rr^r&rr>r2rPr value_changed set_valuer_enqueue)r.rWr'rDrZr\r^r`rbrdrKrTrUrVrg widget_nameindexable_optionsformatted_optionsdefault_valuesrm element_idprotoserde widget_stater0rkr1rhsx         zMultiSelectMixin._multiselectr"cCs td|S)zGet our DeltaGenerator.r")r r:r0r0r1rsOs zMultiSelectMixin.dg)rWr7r'rXrDrYrZr[r\r]r^r_r`rarbrcrdrerKrLrTr7rUrfrVrr-r,)rWr7r'rXrDrErZr[r\r]r^r_r`rarbrcrdrerKrLrTr7rUrfrVrrgrir-r,)r-r") r?r@rArr7rRrhpropertyrsr0r0r0r1rQis@  YrQN)rDrEr-rF)rJrErKrL): __future__rcollections.abcr dataclassesrrtextwraprtypingrrr r r streamlit.dataframe_utilr !streamlit.elements.lib.form_utilsr -streamlit.elements.lib.options_selector_utilsrrrrstreamlit.elements.lib.policiesrrstreamlit.elements.lib.utilsrrrrrrstreamlit.errorsrstreamlit.proto.MultiSelect_pb2rrtstreamlit.runtime.metrics_utilrstreamlit.runtime.scriptrunnerrrstreamlit.runtime.staterstreamlit.type_utilr r!streamlit.delta_generatorr"r#r$r%r&rIrPrQr0r0r0r1s2
