Usage info

Interactive component - see our guide to enabling interactivity.

Unlike the select menu, there is no typeahead field, and the button always appears with an ellipsis ("…") rather than customizable text. As such, it is usually used if you want a more compact layout than a select menu, or to supply a list of less visually important actions after a row of buttons. You can also specify URL links as overflow menu options, instead of actions.

Example:

Fields

Field	Type	Description	Required?
type	String	The type of element. In this case type is always overflow.	Required
action_id	String	An identifier for the action triggered when a menu option is selected. You can use this when you receive an interaction payload to identify the source of the action. Should be unique among all other action_ids in the containing block. Maximum length is 255 characters.	Optional
options	Object[]	An array of up to five option objects to display in the menu.	Required
confirm	Object	A confirm object that defines an optional confirmation dialog that appears after a menu item is selected.	Optional

Example

A section block with an overflow menu:

{
  "type": "section",
  "block_id": "section 890",
  "text": {
    "type": "mrkdwn",
    "text": "This is a section block with an overflow menu."
  },
  "accessory": {
    "type": "overflow",
    "options": [
      {

          "type": "plain_text",
          "text": "*this is plain_text text*"
        },
        "value": "value-0"

      {
