Change display category name programatically

[Jaynil A Bagdai, geändert vor 11 Jahren.]

Hi All,
In Liferay we can provide display category like below in xml file.

<display>
	<category name="category.admin">
		<portlet id="9" />
		<portlet id="40" />
		<portlet id="79" />
		<portlet id="80" />
	</category>
	<category name="category.cms">
		<category name="category.alfresco">
			<portlet id="91" />
		</category>
	</category>
...
<display></display></display>

But what if i want to provide category on some conditions. That means i want to provide category programatically.

How can i do that?
