Many of us enjoy collecting things we value. They may be stamps, comic books, sea shells, or fabulous shoes. The list goes on and on. But have you considered URLs collectible? Having a thorough collection of links can be a great way to add value to your portal’s usability.
With Liferay’s Bookmarks application, users collect and manage URLs in the portal. They can add, edit, delete, export and import bookmarks. Users can use links to access regularly visited web sites. Administrators can publish links tailored to specific groups of users. Both internal pages as well as external sites can be bookmarked.
Navigate to your portal and add the Bookmarks application to your page by selecting Add → Applications. The portlet looks like this by default:
Across the top of the portlet are links labeled Home, Recent, and Mine. There is also a Search field and button.
Home: returns you to the top level of the portlet.
Recent: displays a list of the latest bookmarks that have been added.
Mine: displays a list of the bookmarks you added to the portlet.
Search: lets you search for bookmarks by name, category, or tags.
When you select the Permissions button on the right, a list of Roles and their associated permissions appears. The options are Add Entry, Add Folder, Permissions, and View. When you are finished selecting the permissions, click Save.
Clicking the Add Folder button in the Bookmarks application reveals the New Folder form. Here you can choose the folder’s name, a description of its contents, and who can view it. Under More Options, you can set portlet permissions for various Roles to the folder. Click Save when you are finished.
To create a bookmark, click the Add Bookmark button. This form is similar to the New Folder form but has a few more options.
Click Select to choose the folder for the new bookmark. Click Remove to delete a bookmark from the selected folder. As stated above, a removed link goes into the list of general bookmarks that aren’t associated with a folder. These are listed in the bookmarks section, below the folders, in the portlet.
Below the Permissions there are additional options for Categorization and Related Assets, just like in other Liferay applications. Please see the Displaying Content Dynamically chapter for further information about this.
Once you have added a new bookmark, it appears in the portlet. From here, you can manage your bookmark using familiar Liferay editing features. Collecting and organizing your links is a snap when you use Liferay’s Bookmarks application.
You can store all your important links in one place and you can manage this data easily using folders. You can create, edit, and delete bookmark folders. You get to decide how many bookmarks or folders are displayed on a page. Bookmark folders can have any number of subfolders.
Here’s an example of what one bookmarks portlet might look like. Bookmark Folders are displayed above individual bookmarks.
In this example, there are six bookmark folders, three of which have subfolders. The columns showing the number of folders and the number of entries show the subfolders and the entries contained within each top level folder. Note that total number of bookmarks includes those in the subfolders.
Using the Actions button on the right, you can edit the folder, manage folder permissions, delete the folder, add a subfolder, or add a bookmark to the folder.
As your collection of links grows, you may need to add more subfolders to keep things in order. Should you decide a link needs to move from one folder to another, you can manage this using the Edit option for that link.
Just for fun, let’s move a link from the main bookmarks folder into a subfolder one level down. We’ll move the Liferay link into the Trivia subfolder in the Sports & Games folder. The Trivia subfolder is a child of the Sports & Games folder. We’ll move the link to the Sports & Games folder first before moving it into the Trivia subfolder.
To achieve this, we select Edit from the Actions button for the link. In the Edit view, find the section called Folder. When applicable, this section contains breadcrumb links to allow you to navigate freely among the other folder levels. Currently, there are two buttons here labeled Select and Remove. Click the Select button and a new window appears, like the one below. Clicking the Remove button here doesn’t affect the link. It is used solely for moving links out of folders and subfolders back into the main Bookmarks view.
Now choose the Sports & Games folder. When you do this, notice how the link’s Folder section changes to reflect the new location of the link. When you choose Save, you return to the Bookmarks portlet. Notice that the Liferay link is no longer under the Bookmarks section. Select Sports & Games to reveal its contents. In the example below, you can see the Liferay link is now in the bookmarks section of the Sports & Games folder.
Select Edit from the Actions button next to the Liferay link, then click Select. Navigate to the # of Folders number next to the Sports & Games folder and choose the Trivia subfolder. Again, notice the change in the folder-level breadcrumbs. Click Save and the Sports & Games folder view appears. change in the link’s folder section, which now displays Trivia. Click Save and the Sports & Games folder view appears. Select Trivia to see your link in the subfolder’s bookmarks list. Piece of cake, right?
To move a link out of a subfolder and into a higher-level folder, edit the link in the subfolder and choose Select. In the resulting window, select the appropriate folder from the breadcrumbs at the top. In this example, we selected Sports & Games for consistency. This opens a new window, like the one below, showing the other folder options.
You can choose one of the other subfolders from the list, or you can choose Home from the breadcrumbs at the top. When you verify that the desired folder is the one currently displayed in the breadcrumbs, click Choose This Folder. Then click Save and you’re done. If you don’t like any of the subfolders listed, you can place the link into a new subfolder by using the Add Subfolder button.
If you choose Remove instead of Select in the above example, you take the link out of both subfolders and return it to the main bookmarks view.
Now that you have an understanding of how bookmark folders are used, let’s create our own plugin repository.
