Determines which button (by index starting from 0) is considered active.

Sets the color of the border enclosing the update menu.

Sets the width (in px) of the border enclosing the update menu.

• args
  Parent: layout.updatemenus[].buttons[]
  Type: list

  Sets the arguments values to be passed to the Plotly method set in `method` on click.

• args2
  Parent: layout.updatemenus[].buttons[]
  Type: list

  Sets a 2nd set of `args`, these arguments values are passed to the Plotly method set in `method` when clicking this button while in the active state. Use this to create toggle buttons.

• execute
  Parent: layout.updatemenus[].buttons[]
  Type: boolean
  Default: TRUE

  When TRUE, the API method is executed. When FALSE, all other behaviors are the same and command execution is skipped. This may be useful when hooking into, for example, the `plotly_buttonclicked` method and executing the API command manually without losing the benefit of the updatemenu automatically binding to the state of the plot through the specification of `method` and `args`.

• label
  Parent: layout.updatemenus[].buttons[]
  Type: string
  Default: ""

  Sets the text label to appear on the button.

• method
  Parent: layout.updatemenus[].buttons[]
  Type: enumerated , one of ( "restyle" | "relayout" | "animate" | "update" | "skip" )
  Default: "restyle"

  Sets the Plotly method to be called on click. If the `skip` method is used, the API updatemenu will function as normal but will perform no API calls and will not bind automatically to state updates. This may be used to create a component interface and attach to updatemenu events manually via JavaScript.

• name
  Parent: layout.updatemenus[].buttons[]
  Type: string

  When used in a template, named items are created in the output figure in addition to any items the figure already has in this array. You can modify these items in the output figure by making your own item with `templateitemname` matching this `name` alongside your modifications (including `visible: FALSE` or `enabled: FALSE` to hide it). Has no effect outside of a template.

• templateitemname
  Parent: layout.updatemenus[].buttons[]
  Type: string

  Used to refer to a named item in this array in the template. Named items from the template will be created even without a matching item in the input figure, but you can modify one by making an item with `templateitemname` matching its `name`, alongside your modifications (including `visible: FALSE` or `enabled: FALSE` to hide it). If there is no template or no matching item, this item will be hidden unless you explicitly show it with `visible: TRUE`.

• visible
  Parent: layout.updatemenus[].buttons[]
  Type: boolean

  Determines whether or not this button is visible.

Determines the direction in which the buttons are laid out, whether in a dropdown menu or a row/column of buttons. For `left` and `up`, the buttons will still appear in left-to-right or top-to-bottom order respectively.

• shadow
  Parent: layout.updatemenus[].font
