`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.
`options`	List of lists containing elements 'label', 'value', 'disabled'. those elements have the following types: - label (character \| numeric; required): the checkbox's label - value (character \| numeric; required): the value of the checkbox. 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.s. An array of options
`value`	List of character \| numerics. The currently selected value
`className`	Character. The class of the container (div)
`style`	Named list. The style of the container (div)
`inputStyle`	Named list. The style of the <input> checkbox element
`inputClassName`	Character. The class of the <input> checkbox element
`labelStyle`	Named list. The style of the <label> that wraps the checkbox input and the option's label
`labelClassName`	Character. The class of the <label> that wraps the checkbox input and the option's label
`loading_state`	Lists containing elements 'is_loading', 'prop_name', 'component_name'. those elements have the following types: - is_loading (logical; optional): determines if the component is loading or not - prop_name (character; optional): holds which property is loading - component_name (character; optional): holds the name of the component that is loading. Object that holds the loading state object coming from dash-renderer
`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.
