Description of default Components and FreeMarker information

At this time, there is not a complete list of the default components and description of what they do although I do believe that is coming soon to studio (descriptions at least). There is not a lot of customization that can be done to default components but you can use those components in custom components.  For example, if I wanted to show search only to logged in users

<#if user.registered >  <#-- if the user is not anonymous -->
<@component id="common.widget.search-form" showAdvancedSearchLink="false" />

</#if>

You can use a user avatar with freemarker, you just also need to use our REST API like this:

<#assign avatar = rest("/users/id/[user id]/profiles/avatar").image />
<#if avatar.url?length gt 0>
<img src="${avatar.url}">
</#if>

You will need to replace [user id] with the id of the user whose avatar you want. If you are looking to display the current user's avatar you can use

${user.id}

. Hope that helps.

Edited - I had a longer example but my html is code is being interpreted instead of displayed. I will update when I fix that :)
