public String getType()
```
  - getPlaceholder
```
public PlainTextObject getPlaceholder()
```
    A plain_text only text object that defines the placeholder text shown on the menu. Maximum length for the text in this field is 150 characters.
  - getActionId
```
public String getActionId()
```
    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 used elsewhere by your app. Maximum length for this field is 255 characters.
  - getInitialOptions
```
public List<OptionObject> getInitialOptions()
```
    An array of option objects that exactly match one or more of the options within options or option_groups. These options will be selected when the menu initially loads.
  - getMinQueryLength
```
public Integer getMinQueryLength()
```
    When the typeahead field is used, a request will be sent on every character change. If you prefer fewer requests or more fully ideated queries, use the min_query_length attribute to tell Slack the fewest number of typed characters required before dispatch.
  - getConfirm
```
public ConfirmationDialogObject getConfirm()
```
    A confirm object that defines an optional confirmation dialog that appears before the multi-select choices are submitted.
  - getMaxSelectedItems
```
public Integer getMaxSelectedItems()
```
    Specifies the maximum number of items that can be selected in the menu. Minimum number is 1.
  - getFocusOnLoad
```
public Boolean getFocusOnLoad()
```
    Indicates whether the element will be set to auto focus within the view object. Only one element can be set to true. Defaults to false.
  - setPlaceholder
```
public void setPlaceholder(PlainTextObject placeholder)
```
    A plain_text only text object that defines the placeholder text shown on the menu. Maximum length for the text in this field is 150 characters.
  - setActionId
```
public void setActionId(String actionId)
```
    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 used elsewhere by your app. Maximum length for this field is 255 characters.
  - setInitialOptions
```
public void setInitialOptions(List<OptionObject> initialOptions)
```
    An array of option objects that exactly match one or more of the options within options or option_groups. These options will be selected when the menu initially loads.
  - setMinQueryLength
```
public void setMinQueryLength(Integer minQueryLength)
```
    When the typeahead field is used, a request will be sent on every character change. If you prefer fewer requests or more fully ideated queries, use the min_query_length attribute to tell Slack the fewest number of typed characters required before dispatch.
  - setConfirm
```
public void setConfirm(ConfirmationDialogObject confirm)
```
    A confirm object that defines an optional confirmation dialog that appears before the multi-select choices are submitted.
  - setMaxSelectedItems
```

```
    Specifies the maximum number of items that can be selected in the menu. Minimum number is 1.
  - setFocusOnLoad
```
public void setFocusOnLoad(Boolean focusOnLoad)
```
