[OmniFaces utilities] The
splitList()
function splits the given list into a list of sublists of the given fragment size. This is useful for creating nested <ui:repeat>
structures, for example, when positioning a list of items into a grid based layout system such as Twitter Bootstrap.Function:
Usage:
Let's suppose that we have a managed bean named ColorsBean that contains the following list
of colors:
@Named
@ViewScoped
public class ColorsBean
implements Serializable {
List<String> colors = new
ArrayList<>();
public ColorsBean() {
colors.add("#045FB4");
colors.add("#F781BE");
colors.add("#0B3B0B");
colors.add("#F7819F");
colors.add("#2E2E2E");
colors.add("#B40404");
colors.add("#04B404");
colors.add("#D0A9F5");
colors.add("#FFFF00");
}
public List<String> getColors() {
return
colors;
}
public void setColors(List<String>
colors) {
this.colors = colors;
}
}
Now, as an example, we shape this list via <ul> and <li> like in figure below:
<ul>
<ui:repeat value="#{of:splitList(colorsBean.colors, 3)}"
var="subList">
<li>
<ui:repeat value="#{subList}" var="item">
<div style="color:#{item}">#{item}</div>
</ui:repeat>
</li>
</ui:repeat>
</ul>
