# Customize the Toolbar (Angular)

Survey Creator's toolbar contains buttons that perform actions relevant to the active tab. For instance, the Designer tab allows users to undo and redo last operations, the Preview tab—change the device type and orientation, and the JSON Editor tab—import and export the survey JSON schema. This demo shows how to add a custom toolbar button that clears the survey on the design surface.

## Configure a Toolbar Button

To configure a toolbar button, define an [`IAction`](https://surveyjs.io/form-library/documentation/api-reference/iaction) object. Within it, you can set the button's [unique ID](https://surveyjs.io/form-library/documentation/api-reference/iaction#id), [icon](https://surveyjs.io/form-library/documentation/api-reference/iaction#iconName), [tooltip](https://surveyjs.io/form-library/documentation/api-reference/iaction#tooltip), and other parameters. You should also specify a function that this button will call and assign it to the [`action`](https://surveyjs.io/form-library/documentation/api-reference/iaction#action) property. In this demo, the `action` function sets the Survey Creator's [`JSON`](https://surveyjs.io/survey-creator/documentation/api-reference/survey-creator#JSON) property to an empty object, thus clearing the survey users configure. 

```js
import { Action } from "survey-core";

const clearSurveyAction = new Action({
    id: "clear-survey",
    tooltip: "Clear Survey",
    iconName: "icon-clear-24x24",
    action: () => {
        creator.JSON = {};
    }
});
```

Different tabs can have different toolbar buttons. To control the toolbar button visibility, use the `IAction` object's [`visible`](https://surveyjs.io/form-library/documentation/api-reference/iaction#visible) property. You can set it to a static Boolean value or to a `ComputedUpdater` instance if you need to calculate the property value dynamically. The `ComputedUpdater` constructor accepts a function that specifies the calculation rules. This function will be reevaluated each time a dependency property is changed. In this demo, the `visible` property depends on the Survey Creator's [`activeTab`](https://surveyjs.io/survey-creator/documentation/api-reference/survey-creator#activeTab) property:

```js
const clearSurveyAction = new Action({
    // ...
    visible: new ComputedUpdater(() => creator.activeTab === "designer")
});
```

## Add the Button to the Toolbar

Survey Creator includes two toolbars: top (for the desktop view) and bottom (for the mobile view). You can add your custom button to both or only one of the toolbars: 

```js
// Add a custom button to the top toolbar
creator.toolbar.actions.push(clearSurveyAction);

// Add a custom button to the bottom toolbar
creator.footerToolbar.actions.push(clearSurveyAction);
```
