I want to copy a component from one page to another page in touch UI AEM. How can we achieve that?
One way to do this would be to open html of the page you want to add component on, and perform one of these:
Adding component directly on the page:
<article data-sly-resource="${'componentName' @ prependPath='path/to/the/component'}"></article>
Adding parsys component, and then drag&drop component on that parsys:
<cq:include path="par" resourceType="foundation/components/parsys" />
You can add component on page/template in many different ways that depends on your exact need.
