Syntax

@template( [EL-expression] )

Description

Target Attribute: model, children

Purpose: It should be used with @bind, @load. It determines which template to be used to render child components.

The evaluation result of EL expression should be the name of a template which is used to render child components. The result template's name can be any template defined in the same id space.

Example

Dynamic template upon iteration status variable

<combobox model="@bind(item.options ) @template(forEachStatus.index eq 0 or forEachStatus.index eq 2?'model1':'model2')">
	<template name="model1" var="option" >
		<comboitem label="@bind(optionStatus)" description="@bind(option)"/>	
	</template>
	<template name="model2" var="option" >
		<comboitem label="@bind(optionStatus)" description="@bind(option)"/>	
	</template>
</combobox>

Recursive usage

<vlayout id="vlayout" children="@load(vm.nodes) @template('greenBox')">
	<template name="greenBox" var="node">
		<vlayout style="padding-left:10px; border:2px solid green;" >
			<label value="@bind(node.name)" />
			<vlayout
				children="@load(node.children) @template('greenBox')" />
		</vlayout>
	</template>
</vlayout>

• vm.nodes has a tree-like structure, and node.children is a collection of node.
