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.

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.

<ContentType ID="0x0100fb1027dc96a44bf280f6cb823a8da5ae"
Name="FAQ"
Group="SE"
Description="FAQ Content Type"
Inherits="TRUE"
Version="0">
<FieldRefs>
<FieldRef Name="LinkTitle" ID="{82642ec8-ef9b-478f-acf9-31f7d45fbc31}" DisplayName="Question" Sealed="TRUE"/>
<FieldRef Name="LinkTitleNoMenu" ID="{bc91a437-52e7-49e1-8c4e-4698904b2b6d}" DisplayName="Question" Sealed="TRUE"/>
<FieldRef Name="Title" ID="{fa564e0f-0c70-4ab9-b863-0177e6ddd247}" DisplayName="Question" Sealed="TRUE"/>
<FieldRef ID="{b0747420-54bc-41b2-a1b3-8432f2dbdc70}" Name="Answer"/>
</FieldRefs>
</ContentType>

Custom View for arranging items using jQuery UI Accordion

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

<View BaseViewID="10" Type="HTML" WebPartZoneID="Main" DisplayName="Accordion" DefaultView="FALSE" SetupPath="pages\viewpage.aspx" ImageUrl="/_layouts/images/generic.png" Url="Accordion.aspx">
<Toolbar Type="Standard" />
<XslLink Default="TRUE">FAQ.xsl</XslLink>
<RowLimit Paged="TRUE">30</RowLimit>
<ViewFields>
<FieldRef Name="Title" ID="{fa564e0f-0c70-4ab9-b863-0177e6ddd247}" DisplayName="Question" Sealed="TRUE"/>
<FieldRef Name="Answer" ID="{b0747420-54bc-41b2-a1b3-8432f2dbdc70}"></FieldRef>
</ViewFields>
<Query>
<OrderBy>
<FieldRef Name="ID"></FieldRef>
</OrderBy>
</Query>
<ParameterBindings/>
</View>

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
<xsl:stylesheet xmlns:x="http://www.w3.org/2001/XMLSchema"

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.

<xsl:template name="FAQViewOverride" mode="RootTemplate" match="View[List/@TemplateType=11999]" ddwrt:dvt_mode="root">
<link rel="stylesheet" href="http://ajax.aspnetcdn.com/ajax/jquery.ui/1.8.10/themes/redmond/jquery-ui.css" />
<script src="http://ajax.aspnetcdn.com/ajax/jquery/jquery-1.8.0.js"></script>
<script src="http://ajax.aspnetcdn.com/ajax/jquery.ui/1.8.22/jquery-ui.js"></script>
<script>
$(function() {
$( "#accordionFAQ" ).accordion();
});
</script>
<xsl:call-template name="View_Default_RootTemplate"/>
</xsl:template>
