Parameters ---------- label : str A short label explaining to the user what this select widget is for. The label can optionally contain Markdown and supports the following elements: Bold, Italics, Strikethroughs, Inline Code, Emojis, and Links. This also supports: * Emoji shortcodes, such as ``:+1:`` and ``:sunglasses:``. For a list of all supported codes, see https://share.streamlit.io/streamlit/emoji-shortcodes. * LaTeX expressions, by wrapping them in "$" or "$$" (the "$$" must be on their own lines). Supported LaTeX functions are listed at https://katex.org/docs/supported.html. * Colored text, using the syntax ``:color[text to be colored]``, where ``color`` needs to be replaced with any of the following supported colors: blue, green, orange, red, violet. Unsupported 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``. For accessibility reasons, you should never set an empty label (label="") but hide it with label_visibility if needed. In the future, we may disallow empty labels by raising an exception. options : Sequence, numpy.ndarray, pandas.Series, pandas.DataFrame, or pandas.Index Labels for the select options. This will be cast to str internally by default. For pandas.DataFrame, the first column is selected. index : int The index of the preselected option on first render. format_func : function Function to modify the display of the labels. It receives the option as an argument and its output will be cast to str. 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. Multiple widgets of the same type may not share the same key. help : str An optional tooltip that gets displayed next to the selectbox. on_change : callable An optional callback invoked when this selectbox'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. disabled : bool An optional boolean, which disables the selectbox if set to True. The default is False. This argument can only be supplied by keyword. label_visibility : "visible" or "hidden" or "collapsed" The visibility of the label. If "hidden", the label doesn't show but there is still empty space for it above the widget (equivalent to label=""). If "collapsed", both the label and the space are removed. Default is "visible". This argument can only be supplied by keyword. Returns ------- any The selected option Example ------- >>> import streamlit as st >>> >>> option = st.selectbox( ... 'How would you like to be contacted?', ... ('Email', 'Home phone', 'Mobile phone')) >>> >>> st.write('You selected:', option) .. output:: https://doc-selectbox.streamlitapp.com/ height: 320px ) r<r"r#r=r>r?r@rArBr:r;ctx)r _selectbox) r(r<r"r#r=r>r?r@rArBr:r;rCr)r)r*r9Gs`zSelectboxMixin.selectbox)r:r;rC) r<r"r#r=r>r?r@rArBr:r;rCr%c  s>t|}t|j|t|dkr"dn||dt|| t|} t|tsZtdt |j t | dkrd|kr~t | ksntdt }||_ ||_fdd| D|jdd<t|j|_|dk rt||_t| |}td||||| |j|j| d }| |_t| |j_|jr*||j|_d |_|jd||jS) Nr) default_valuer>z$Selectbox Value has invalid type: %sz7Selectbox index must be between 0 and length of optionscsg|]}t|qSr))r7).0optionr=r)r* sz-SelectboxMixin._selectbox..r9)Zuser_keyZon_change_handlerrArBZ deserializer serializerrCT)rr dgr rr isinstancer5rtyper1r'SelectboxProtor<defaultr"r Zform_idrr?r!rr0r+r:rr;value value_changed set_valueZ_enqueue)r(r<r"r#r=r>r?r@rArBr:r;rCoptZselectbox_protoZserdeZ widget_stater)rHr*rDsR    &   zSelectboxMixin._selectboxr )r%cCs td|S)zGet our DeltaGenerator.r )r )r(r)r)r*rKszSelectboxMixin.dg)r1r2r3rr7rrr5rrrrrrrboolrr9rrDpropertyrKr)r)r)r*r8Fsj  s   Er8N)/Z dataclassesrtextwraprtypingrrrrrr r Zstreamlit.elements.formr Zstreamlit.elements.utilsr r rZstreamlit.errorsrZstreamlit.proto.Selectbox_pb2rrNZstreamlit.runtime.metrics_utilrZstreamlit.runtime.scriptrunnerrrZstreamlit.runtime.staterrrrZstreamlit.type_utilrrrrrrrZstreamlit.utilrZstreamlit.delta_generatorr r!r8r)r)r)r*s  $    $
