nNote These plugins change periodically. If you do not find the Envision theme listed on your screen,

select any available theme for the purposes of this exercise.

Selecting the theme displays the product information on the next screen (see Figure 2-14).

Click the Install button to download and install the theme. After the theme downloads

successfully, you will get a Done message at the bottom of the screen, after which Liferay

performs the installation. It takes a few seconds to install the theme on the server; you can

monitor the installation process on the web-server console. Once the theme has deployed suc￾cessfully, return to the full-page view of your portal.

You can now apply the new theme to a page of your choice. When you drill down to the

Themes option in your Manage Pages application, you will see the newly added theme as

shown in Figure 2-15.

through your Liferay portal. But you’ll need to follow a different process to use themes from

Liferay’s user communities. I’ll discuss that next.
