Inheritance

DropdownListControl extends StockControl.

DropdownListControl is extended by ComparisonControl, DataSaveControl, IndicatorControl, IntervalControl, SeriesTypeControl, SettingsControl.

Settings

Set these settings on a DropdownListControl object using its set() and setAll() methods. Read about settings concept.

#currentItem

Type string | IDropdownListItem

Item (or its ID) shown as selected when the control is created. It is not updated when another item is picked.

#exclude

Type string[]Since 5.7.0

IDs of items to leave out of the list.

#fixedLabel

Type undefined | false | true

Keeps the button's label and icon when an item is picked, instead of showing that item.

#items

Type Array

Items of the dropdown: strings, or objects with an id and a label.

#maxSearchItems

Type undefined | number

Most results of searchCallback to show; the rest are cut off with a note.

#scrollable

Type undefined | false | true

Limits the list's height to the chart's height minus 100 pixels, scrolling the rest.

#searchable

Type undefined | false | true

Shows a search field above the list. Typing filters the items or, with searchCallback, replaces them with its results.

#searchCallback

Type undefined | (query: string) => IDropdownListItem[]

Returns the items to show for a search query.

18 inherited items

#active

Type undefined | false | trueDefault falseInherited from IStockControlSettings

Turns the control on; its button shows as active.

#align

Type "left" | "right"Default "left"Inherited from IStockControlSettings

Side of the toolbar the control is placed on.

#animations

Type ArrayInherited from IEntitySettingsSince 5.20.8

Animations the element plays on its own, described as data - so they can be set from a JSON config and saved with it.

Each one animates a setting of the element (or, with target: "dataItem", a value of its data item - a map point's positionOnLine, say). They start when the setting is applied, restart when it changes, and stop when the element is disposed. A saved config keeps what was configured, never a value caught half way through an animation.

sprite.set("animations", [
  { key: "rotation", to: 360, duration: 4000, loops: 0 },
  { key: "scale", from: 1, to: 1.3, duration: 800, loops: 0, yoyo: true, easing: "sine" }
]);
