size=NULL, html_size=NULL, persistence=NULL,

Arguments

id	Character. The ID of this component, used to identify dash components in callbacks. The ID needs to be unique across all of the components in an app.
style	Named list. Defines CSS styles which will override styles previously set.
class_name	Character. Often used with CSS to style elements with common properties.
className	Character. **DEPRECATED** Use 'class_name' instead. Often used with CSS to style elements with common properties.
key	Character. A unique identifier for the component, used to improve performance by React.js while rendering components See https://reactjs.org/docs/lists-and-keys.html for more info
placeholder	Character. Placeholder text to display before a selection is made.
value	Character | numeric. The value of the currently selected option.
options	List of lists containing elements 'label', 'value', 'disabled', 'title'. those elements have the following types: - label (character | numeric; required): the options's label - value (character; required): the value of the option. this value corresponds to the items specified in the 'value' property. - disabled (logical; optional): if true, this checkbox is disabled and can't be clicked on. - title (character; optional): the html 'title' attribute for the option. allows for information on hover. for more information on this attribute, see https://developer.mozilla.org/en-us/docs/web/html/global_attributes/titles. An array of options for the select
disabled	Logical. Set to True to disable the Select.
required	A value equal to: 'required', 'required' | logical. This attribute specifies that the user must fill in a value before submitting a form. It cannot be used when the type attribute is hidden, image, or a button type (submit, reset, or button). The :optional and :required CSS pseudo-classes will be applied to the field as appropriate. required is an HTML boolean attribute - it is enabled by a boolean or 'required'. Alternative capitalizations 'REQUIRED' are also acccepted.
valid	Logical. Apply valid style to the Input for feedback purposes. This will cause any FormFeedback in the enclosing div with valid=True to display.
invalid	Logical. Apply invalid style to the Input for feedback purposes. This will cause any FormFeedback in the enclosing div with valid=False to display.
size	Character. Set the size of the Input. Options: 'sm' (small), 'md' (medium) or 'lg' (large). Default is 'md'.
html_size	Character. This represents the number of rows in the select that should be visible at one time. It will result in the Select being rendered as a scrolling list box rather than a dropdown.
persistence	Logical | character | numeric. Used to allow user interactions in this component to be persisted when the component - or the page - is refreshed. If 'persisted' is truthy and hasn't changed from its previous value, a 'value' that the user has changed while using the app will keep that change, as long as the new 'value' also matches what was given originally. Used in conjunction with 'persistence_type'.
persisted_props	List of a value equal to: 'value's. Properties whose user interactions will persist after refreshing the component or the page. Since only 'value' is allowed this prop can normally be ignored.
persistence_type	A value equal to: 'local', 'session', 'memory'. Where persisted user changes will be stored: memory: only kept in memory, reset on page refresh. local: window.localStorage, data is kept after the browser quit. session: window.sessionStorage, data is cleared once the browser quit.
name	Character. The name of the control, which is submitted with the form data.

Value

named list of JSON elements corresponding to React.js properties and their values
