Customize the rendering of a List View in Sharepoint 2010: Displaying List Items in Accordion

Overview

The creation of non standard presentations for Lists/Libraries  is a fairly common  scenario and using the XSLT List View Web Part (XLV) possibilities that can be achieved pretty easily.
Let’s take a look how to render list of question and answers using Accordion Menu in SharePoint. Actually the idea for this post appeared after posting  of corresponding question on StackOverflow.
So, let’s discuss how it could be accomplished using XLV. For Accordion we will utilize jQuery UI library.

Accordion

Implementation

FAQ Custom List

First of all, let us define where  the questions and answers (FAQ) we’ll be stored. For this we will use Custom List with Content Type.

Custom View for arranging items using jQuery UI Accordion

After creating Custom List we add new View for displaying Accordion for FAQ items

XSLT style sheet for rendering Accordion View

XSLT style sheet for FAQ List is intended for the following purposes:

  • loading jQuery Core and UI Libraries
  • rendering list items using layout as specified for Accordion menu
  • initializing and rendering Accordion for List items

Using jQuery UI Accordion

jQuery Core and UI libraries are injected during XSLT style sheet processing. After JavaScript files which hosted on Microsoft CDN are loaded, jQuery UI Accordion is initialized for items.

Embedding and Sharing Video in SharePoint

Introduction

The solution described here allows to embed video hosted on YouTube into SharePoint. The same approach may be applied for embedding video from another video hosting sites, for example from Vimeo.

The main idea here to store embedded video properties and not the embedded code itself.
For storing embedded video properties we will use Custom  List, see implementation section for description. Page for Video Links list (default view with embedded player)  is shown below

Usage

In order to embed a video into SharePoint:

  • On YouTube site click the Share button located under the video.
  • Click the Embed button.
  • Copy at least src attribute value provided in the expanded box (see table 1 for supported attributes).

  • Create new Video Link item  and paste attribute values for embedded code into Video Links item. Save it.

Table 1. Mapping between embedded code iframe attributes and Video Link item

Attribute name Video Links field name
src URL
width Video Width
height Video Height
allowfullscreen Allow Fullscreen
frameborder Frame Border

Video Links implementation

As was mentioned earlier only properties for embedded video code are stored and not the embedded code itself. For storing embedded video code properties is used Custom List that extends OOB Links List (TemplateType = 103)

For embedded video properties we create Video Link Content Type that inherits from Link CT (0x0105)

where we define the following fields

Pay attention, for rendering YouTube player Computed Field EmbeddedVideoOnForm is intended.
For rendering of a field on a List View the following XSLT style sheet is used

And finally, we create List Definition Video Links from Content Type Video Link. List schema and Template files for Video Links including whole project  may be found on GitHub.
