Tab configuration

The form-based content editor allows content fields to be organized in tabs. Which field is shown in which tab can be configured in the content schema document.

Configuration of tabs

Tabs are configured in the schema definition under xsd:annotations/xsd:appinfo using the <tabs> element. If used without sub-nodes, the tabs are configured automatically. To set up the tabs explicitly according to your needs, use a sub-node <tab> for each of them:

<tabs>
    <tab element="Title" collapse="false" name="General" />
    <tab element="Author" collapse="false" name="AuthorTab" />
    <tab element="Availability" collapse="true" name="Availability">
        <description>In this tab you can configure release and expiration dates.</description>
    </tab>
</tabs>

In the example, three tabs are defined. Each <tab> element is configured via its attributes as follows:

element: Name of the first <xsd:element> placed in the tab.
collapse: If only one element (typically a nested content with sub-elements) should appear in one tab, the element's name can be hidden. Therefore, set collapse="true". Otherwise, omit it, or set it to false.
name: Define the name shown in the tab. If the attribute is not given, the element's name is used as the tab name. To localize the tab name, use the key macro, e.g., place %(key.{name of the key}). The key must reside in a workplace bundle.

When configuring tabs explicitly, the first tab should always start with the first schema element of your content. Otherwise OpenCms will add an additional first tab automatically.

<tab> elements may contain an optional sub-node <description>. If provided, the text inside this node is displayed as extra information at the very top of a tab. Use the %(key.) macro for localized descriptions in combination with a key from a workplace bundle.
