    """A Dropdown component.
 | 
			
		||||
    Dropdown is an interactive dropdown element for selecting one or more
 | 
			
		||||
    items.
 | 
			
		||||
    The values and labels of the dropdown items are specified in the `options`
 | 
			
		||||
    property and the selected item(s) are specified with the `value` property.
 | 
			
		||||
 | 
			
		||||
    Use a dropdown when you have many options (more than 5) or when you are
 | 
			
		||||
    constrained for space. Otherwise, you can use RadioItems or a Checklist,
 | 
			
		||||
    which have the benefit of showing the users all of the items at once.
 | 
			
		||||
 | 
			
		||||
    Keyword arguments:
 | 
			
		||||
 | 
			
		||||
    - options (list of dicts; optional):
 | 
			
		||||
        An array of options {label: [string|number], value:
 | 
			
		||||
        [string|number]}, an optional disabled field can be used for each
 | 
			
		||||
        option.
 | 
			
		||||
 | 
			
		||||
        `options` is a list of string | number | booleans | dict | list of
 | 
			
		||||
        dicts with keys:
 | 
			
		||||
 | 
			
		||||
        - label (a list of or a singular dash component, string or number; required):
 | 
			
		||||
            The option's label.
 | 
			
		||||
 | 
			
		||||
        - value (string | number | boolean; required):
 | 
			
		||||
            The value of the option. This value corresponds to the items
 | 
			
		||||
            specified in the `value` property.
 | 
			
		||||
 | 
			
		||||
        - disabled (boolean; optional):
 | 
			
		||||
            If True, this option is disabled and cannot be selected.
 | 
			
		||||
 | 
			
		||||
        - title (string; 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/title.
 | 
			
		||||
 | 
			
		||||
        - search (string; optional):
 | 
			
		||||
            Optional search value for the option, to use if the label is a
 | 
			
		||||
            component or provide a custom search value different from the
 | 
			
		||||
            label. If no search value and the label is a component, the
 | 
			
		||||
            `value` will be used for search.
 | 
			
		||||
 | 
			
		||||
    - value (string | number | boolean | list of string | number | booleans; optional):
 | 
			
		||||
        The value of the input. If `multi` is False (the default) then
 | 
			
		||||
        value is just a string that corresponds to the values provided in
 | 
			
		||||
        the `options` property. If `multi` is True, then multiple values
 | 
			
		||||
        can be selected at once, and `value` is an array of items with
 | 
			
		||||
        values corresponding to those in the `options` prop.
 | 
			
		||||
 | 
			
		||||
    - multi (boolean; default False):
 | 
			
		||||
        If True, the user can select multiple values.
 | 
			
		||||
 | 
			
		||||
    - clearable (boolean; default True):
 | 
			
		||||
        Whether or not the dropdown is \"clearable\", that is, whether or
 | 
			
		||||
        not a small \"x\" appears on the right of the dropdown that
 | 
			
		||||
        removes the selected value.
 | 
			
		||||
 | 
			
		||||
    - searchable (boolean; default True):
 | 
			
		||||
        Whether to enable the searching feature or not.
 | 
			
		||||
 | 
			
		||||
    - search_value (string; optional):
 | 
			
		||||
        The value typed in the DropDown for searching.
 | 
			
		||||
 | 
			
		||||
    - placeholder (string; optional):
 | 
			
		||||
        The grey, default text shown when no option is selected.
 | 
			
		||||
 | 
			
		||||
    - disabled (boolean; default False):
 | 
			
		||||
        If True, this dropdown is disabled and the selection cannot be
 | 
			
		||||
        changed.
 | 
			
		||||
 | 
			
		||||
    - closeOnSelect (boolean; default True):
 | 
			
		||||
        If False, the menu of the dropdown will not close once a value is
 | 
			
		||||
        selected.
 | 
			
		||||
 | 
			
		||||
    - optionHeight (number; default 35):
 | 
			
		||||
        height of each option. Can be increased when label lengths would
 | 
			
		||||
        wrap around.
 | 
			
		||||
 | 
			
		||||
    - maxHeight (number; default 200):
 | 
			
		||||
        height of the options dropdown.
 | 
			
		||||
 | 
			
		||||
    - className (string; optional):
 | 
			
		||||
        className of the dropdown element.
 | 
			
		||||
 | 
			
		||||
    - id (string; optional):
 | 
			
		||||
        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.
 | 
			
		||||
 | 
			
		||||
    - persistence (boolean | string | number; optional):
 | 
			
		||||
        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; default ['value']):
 | 
			
		||||
        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'; default 'local'):
 | 
			
		||||
        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."""
