There are two ways of showing a download/package.
1. Link template ( using shortcode ) – There are multiple link templates available. Each one has its own layout. Use TinyMCE addon to insert shortcode, you will find the option there to select the link template.
2. Page Template – This is the details page for the package/download. You see this page when previewing the package. You can set this details page url in your link template. Clicking on the title ( in link template ) brings the user to the details page.
