Creating an AEM Headline component

You can create an Adobe Experience Manager (AEM) Headline component that you can use in your AEM web page. A headline component lets you website visitors view latest headlines about a specific subject. That is, you can enter keyword into an AEM dialog and the component will display headlines related to the keyword. For example, you can enter Facebook keyword and the component displays headlines, as shown in the following illustration.
