Initializes a helper object (defined in JavaScript or Java) and exposes it through a variable.
- Use another resource
<div data-sly-use.nav="navigation.js">${nav.foo}</div>- Use a java class that is in an OSGi bundle
<div data-sly-use.nav="org.example.Navigation">${nav.foo}</div>- Initialize another Sightly template that can then be called using data-sly-call
<div data-sly-use.nav="navTemplate.html" data-sly-call="${nav.foo}"></div>Removes the host element from the generated markup while retaining its content.
- Simple example
<p data-sly-use.nav="navigation.js" data-sly-unwrap>Hello World</p>produces
Hello world- Conditionally unwrap an element
<div class="popup" data-sly-unwrap="${isPopup}">content</div>Replaces the content of its host element with the specified text
Example to populate the jcr:description in a paragraph
<p data-sly-text="${properties.jcr:description}">Lorem ipsum</p>Adds attributes to the host element
Example to populate the title attribute with jcr:title. The advantage is that if jcr:title is not present or is empty, "Lorem Ipsum" is shown as the fallback title.
<div title="Lorem Ipsum" data-sly-attribute.title="${properties.jcr:title}"></div>- An attribute whose value evaluates to the empty string will be removed in the final markup.
