This component acts as a wrapper and controls the display of items to be contained
within a ToolsPanel. An item is displayed if it is flagged as a default control
or the corresponding panel menu item, provided via context, is toggled on for
this item.

Usage

See tools-panel/README.md#usage
for how to use ToolsPanelItem.

Props

hasValue: () => boolean

This is called when building the ToolsPanel menu to determine the item’s
initial checked state.

• Required: Yes

isShownByDefault: boolean

This prop identifies the current item as being displayed by default. This means
it will show regardless of whether it has a value set or is toggled on in the
panel’s menu.

• Required: No
• Default: false

label: string

The supplied label is dual purpose.
It is used as:
1. the human-readable label for the panel’s dropdown menu
2. a key to locate the corresponding item in the panel’s menu context to
determine if the panel item should be displayed.

A panel item’s label should be unique among all items within a single panel.

• Required: Yes

onDeselect: () => void

Called when this item is deselected in the ToolsPanel menu. This is normally
used to reset the panel item control’s value.

• Required: No

onSelect: () => void

A callback to take action when this item is selected in the ToolsPanel menu.

• Required: No

panelId: string | null

Panel items will ensure they are only registering with their intended panel by
comparing the panelId props set on both the item and the panel itself, or if the panelId is explicitly null. This
allows items to be injected from a shared source.

• Required: No

resetAllFilter: ( attributes?: any ) => any

A ToolsPanel will collect each item’s resetAllFilter and pass an array of
these functions through to the panel’s resetAll callback. They can then be
iterated over to perform additional tasks.

• Required: No
• Default: () => {}
