ContextMenu control

A control used to input commands.

Note

Full documentation and source code found in the GitHub code components repository.

Description

A contextual menu (ContextMenu) is a list of commands that are based on the context of selection, mouse hover, or keyboard focus. They're one of the most effective and highly used command surfaces, and can be used in various places.

This code component provides a wrapper around the Fluent UI ContextualMenu control bound to a button for use in canvas apps and custom pages.

Properties

Key Properties

Property	Description
Items	The action items to render. The first item is considered the root item.

Items Properties

Name	Description
ItemDisplayName	The Display Name of the menu item.
ItemKey	The key to use to indicate which item is selected, and when adding sub items. The keys must be unique.
ItemEnabled	Set to false if the option is disabled.
ItemVisible	Set to false if the option is not visible.
ItemChecked	Set to true if the option is checked.
ItemIconName	The Fluent UI icon to use (see Fluent UI icons)
ItemIconColor	The color to render the icon as (e.g. named, rgb or hex value).
ItemIconOnly	Do not show the text label - only the icon.
ItemHeader	Render the item as a section header. If there are items that have their ItemParentKey set to the key of this item, then they are added as semantically grouped items under this section.
ItemTopDivider	Render a divider at the top of the section.
ItemDivider	Render the item as a section divider - or if the item is a header (ItemHeader = true), then controls whether to render a divider at the bottom of the section.
ItemParentKey	Render the option as child item of another option.

Note

• ItemIconColor will override the component's Theme value and ignore other state colors (e.g., disabled).
• ItemHeader and ItemDivider must be set to true to render as a divider. If set to false, it expects other values and will render blank.
• Adding the ItemChecked property and behavior of submenu items will prevent the submenu from closing on click.

          ItemOverflow:true
      },
       {
          ItemKey: "Delete",

Event Properties

Property	Description
InputEvent	An event to send to the control. E.g. SetFocus. See below.

Behavior

Supports SetFocus as an InputEvent.

Configure 'On Select' behavior

Use the Switch() formula in the component's OnSelect property to configure specific actions for each item by referring to the control's selected ItemKey as the switch value.

Replace the false values with appropriate expressions in the Power Fx language.

  Switch( Self.Selected.ItemKey,
    /* Action for ItemKey 1 */
    "File", false,
    
    /* Action for ItemKey 2 */
    "Delete", false,
  
    /* Default action */
        false
  )

Setting Focus on the control

When a new dialog is shown, and the default focus should be on the control, an explicit set focus will be needed.

To make calls to the input event, you can set a context variable that is bound to the Input Event property to a string that starts with SetFocus and followed by a random element to ensure that the app detects it as a change.

E.g.

UpdateContext({ctxResizableTextareaEvent:"SetFocus" & Text(Rand())}));

The context variable ctxResizableTextareaEvent would then be bound to the property Input Event property.

Limitations

This code component can only be used in canvas apps and custom pages.
