Introduction to Primefaces SplitButton

Primefaces SplitButton is a UI component of the Primefaces library that allows us to create a button with a dropdown menu. It provides both an action button and a dropdown button, providing a simple and effective way to include additional functionality in your web application.

Features

Some of the features of Primefaces SplitButton are:

• Both the action and the dropdown buttons can have their own icon, label, and style.
• The split button can be used to trigger one action or multiple actions using the dropdown menu.
• The dropdown menu can contain submenus and can have different display modes, such as inline, overlay, and dynamic.

Getting Started

To use Primefaces SplitButton in your web application, you need to include the Primefaces library in your project. You can do this by adding the following dependencies to your pom.xml file:

<dependency>
    <groupId>org.primefaces</groupId>
    <artifactId>primefaces</artifactId>
    <version>11.4</version>
</dependency>

After adding the dependencies, you can use the SplitButton component in your web page as follows:

<p:splitButton value="Save" model="#{splitButtonView.buttonModel}" icon="pi pi-check">
    <p:menuitem value="Update" icon="pi pi-refresh" />
    <p:menuitem value="Delete" icon="pi pi-times" />
    <p:menuitem value="Save" icon="pi pi-save" />
</p:splitButton>

In this example, the value attribute sets the label of the action button, the model attribute sets the menu items of the dropdown menu, and the icon attribute sets the icon of the action button.

Conclusion

Primefaces SplitButton provides a useful way of adding dropdown functionality to your web application. With its customizable features and easy-to-use syntax, you can quickly and easily create split buttons that suit your application's needs.
