There are several ways to add assets to your site’s Favorites list in the Assets panel.
Adding a color or URL to the Favorites list requires an extra step. You can’t add new colors or URLs to the Site list; the Site list contains only assets that are already in use in your site.
Do one of the following:
Select one or more assets in the Site list of the Assets
panel, then click the Add To Favorites button .
Select one or more assets in the Site list of the Assets panel, right-click (Windows) or Control-click (Macintosh), then select Add To Favorites.
Select one or more files in the Files panel, right-click (Windows) or Control-click (Macintosh), then select Add To Favorites. Dreamweaver ignores files that don’t correspond to a category in the Assets panel.
Right-click (Windows) or Control-click (Macintosh) an element in the Document window’s Design view, then select the context menu command to add the element to a Favorites category.
The context menu for text contains either Add To Color Favorites or Add To URL Favorites, depending on whether the text has a link attached. You can add only those elements that match one of the categories in the Assets panel.
Select a color using the color picker, then give the color a nickname if desired.
To close the color picker without selecting a color, press Esc or click the gray bar at the top of the color picker.
Enter a URL and a nickname in the Add New URL dialog box, then click OK.
