UXML element ToolbarPopupSearchField

A ToolbarPopupSearchField is an Editor-only control that serves as a search field with a popup menu. It’s a combination of a ToolbarMenu and ToolbarSearchField. You can add logic to the dropdown menu to filter the search results. To pop up the menu, the user hovers over the magnifying glass icon.

Create a ToolbarPopupSearchField

You can create a ToolbarPopupSearchField with UI(User Interface) Allows a user to interact with your application. Unity currently supports three UI systems. More info
See in Glossary Builder, UXML, or C#. The following C# example creates a ToolbarPopupSearchField with a menu, a placeholder text, and a value changed callback:

using UnityEditor.UIElements;
...
var toolbarPopupSearchField = new ToolbarPopupSearchField();
toolbarPopupSearchField.value = "Search me";
toolbarPopupSearchField.menu.AppendAction("Action 1", action => Debug.Log("Action 1"));
toolbarPopupSearchField.menu.AppendAction("Action 2", action => Debug.Log("Action 2"));
toolbarPopupSearchField.RegisterValueChangedCallback(evt => Debug.Log("New search value: " + evt.newValue));

C# base class and namespace

C# class: ToolbarPopupSearchField
Namespace: UnityEditor.UIElements
Base class: ToolbarSearchField

Inherited UXML attributes

This element inherits the following attributes from its base class:

Name	Type	Description
`focusable`	`boolean`	True if the element can be focused.
`tabindex`	`int`	An integer used to sort focusables in the focus ring. Must be greater than or equal to zero.

This element also inherits the following attributes from VisualElement:

Name	Type	Description
`content-container`	`string`	Child elements are added to it, usually this is the same as the element itself.
`data-source`	`Object`	Assigns a data source to this VisualElement which overrides any inherited data source. This data source is inherited by all children.
`data-source-path`	`string`	Path from the data source to the value.
`data-source-type`	`System.Type`	The possible type of data source assignable to this VisualElement. This information is only used by the UI Builder as a hint to provide some completion to the data source path field when the effective data source cannot be specified at design time.
`language-direction`	`UIElements.LanguageDirection`	Indicates the directionality of the element’s text. The value will propagate to the element’s children. Setting the languageDirection to RTL adds basic support for right-to-left (RTL) by reversing the text and handling linebreaking and word wrapping appropriately. However, it does not provide comprehensive RTL support, as this would require text shaping, which includes the reordering of characters, and OpenType font feature support. Comprehensive RTL support is planned for future updates, which will involve additional APIs to handle language, script, and font feature specifications. To enhance the RTL functionality of this property, users can explore available third-party plugins in the Unity Asset Store and make use of `ITextElementExperimentalFeatures.renderedText`
`name`	`string`	The name of this VisualElement. Use this property to write USS selectors that target a specific element. The standard practice is to give an element a unique name.
`picking-mode`	`UIElements.PickingMode`	Determines if this element can be pick during mouseEvents or `IPanel.Pick` queries.
`style`	`string`	Sets the `VisualElement` style values.
`tooltip`	`string`	Text to display inside an information box after the user hovers the element for a small amount of time. This is only supported in the Editor UI.
`usage-hints`	`UIElements.UsageHints`	A combination of hint values that specify high-level intended usage patterns for the `VisualElement`. This property can only be set when the `VisualElement` is not yet part of a `Panel`. Once part of a `Panel`, this property becomes effectively read-only, and attempts to change it will throw an exception. The specification of proper `UsageHints` drives the system to make better decisions on how to process or accelerate certain operations based on the anticipated usage pattern. Note that those hints do not affect behavioral or visual results, but only affect the overall performance of the panel and the elements within. It’s advised to always consider specifying the proper `UsageHints`, but keep in mind that some `UsageHints` might be internally ignored under certain conditions (e.g. due to hardware limitations on the target platform).
`view-data-key`	`string`	Used for view data persistence, such as tree expanded states, scroll position, or zoom level. This key is used to save and load the view data from the view data store. If you don’t set this key, the persistence is disabled for the associated `VisualElement`. For more information, refer to View data persistence.
