java - ZK iterate through list of lists -

i'm totally new zk framework , i'm not sure if info i've provided plenty or not.

i'm aware that, if there fixed number of categories, in .zul file - each groupbox, listbox can displayed.

currently, have list of users beingness displayed categorically i.e there dynamic number categories , each category has dynamic number of users. beingness implemented , displayed using vlayout.

there requirement if there more 10 users in each category, should display 10 users , provide button (or similar) display more users in same category.

my questions are-

is possible accomplish requirement using vlayout? if not, can iterate through list of groupboxs display listbox (list of users) each groupbox (category) in .zul file? or there simpler / more efficient way of achieving requirement?

any suggestions much appreciated.

yes, can refer article utilize "foreach" , "if" tag vlayout or listbox.

for example,

<template name="tree"> <foreach items="@load(vm.authors)" end="10" var="author"> <vlayout> // omitted </vlayout> </foreach> <if test="@load(not empty vm.authors , vm.authors.size() gt 10)"> <span>more...</span> </if> </template>
