+# Add Save button in Built-In Toolbar
+
+PDF Viewer allows you to customize(add, show, hide, enable, and disable) existing items in a toolbar.
+
+* Save button - New 'save' button-item can defined by [**CustomToolbarItemModel**](https://ej2.syncfusion.com/javascript/documentation/api/pdfviewer/customToolbarItem/) and with existing items in [**ToolbarSettings**](https://ej2.syncfusion.com/javascript/documentation/api/pdfviewer/toolbarSettings/) property. Newly added save button-item click action can be defined in [`toolbarclick`](https://ej2.syncfusion.com/javascript/documentation/api/toolbar/clickEventArgs/).
+
+* Show, Hide - save button-item can be shown or hidden using the [`ToolbarSettings`](https://ej2.syncfusion.com/javascript/documentation/api/pdfviewer/toolbarSettings/) property. Pre-defined toolbar items are available with [`ToolbarItem`](https://ej2.syncfusion.com/javascript/documentation/api/pdfviewer/toolbarItem/).
+
+* Enable, Disable -  Toolbar items can be enabled or disable using [`enabletoolbaritem`](https://ej2.syncfusion.com/javascript/documentation/api/pdfviewer/toolbar/#enabletoolbaritem)

+### Align Property
+
+The align property is used to specify the alignment of a `save` button-item within the toolbar.
+
+`Left`: Aligns the item to the left side of the toolbar.
+`Right`: Aligns the item to the right side of the toolbar.
+
+### Tooltip Property
+
+The tooltip property is used to set the tooltip text for a `save` button-item. Tooltip provides additional information when a user hovers over the item.
+
+### CssClass Property
+
+The cssClass property is used to apply custom CSS classes to a `save` button-item. It allows custom styling of the `save` button-item.
+
+### Prefix Property
+
+The prefix property is used to set the CSS class or icon that should be added as a prefix to the existing content of the `save` button-item.
+
+### ID Property
+
+The id property within a CustomToolbarItemModel is a compulsory attribute that plays a vital role in toolbar customization. It serves as a unique identifier for each toolbar item, facilitating distinct references and interactions.
+
+When defining or customizing toolbar items, it is mandatory to assign a specific and descriptive id to each item. 
+These properties are commonly used when defining custom toolbar items with the `CustomToolbarItemModel`` in the context of Syncfusion PDF Viewer. When configuring the toolbar using the `ToolbarSettings`` property, you can include these properties to customize the appearance and behavior of each toolbar item.
+
+N> When customizing save button-item, you have the flexibility to include either icons or text based on your design preference.
