is there any example of dynamic menu?
Do you mean a menu created from a database ?
If you already had defined the menu structure in your database, just create the menu items in this way:
1) Create a menubar object
2) Create a menu object by each main option in your menu (submenus)
3) Add a menuitem for each option in your submenu(2)
You can also used El expressions, databind ans so on...
I still do not understand you have some example that I use, I am putting down the code I'm using to make the menu but it does not come from the database, the Zk live Demo is an example menu http://www.zkoss .org/zkdemo/userguide/#t1, but this example does not bring the resources.
<zk>
<window
apply="br.com.gm.apresentacao.ALogin">
<menubar>
<menuitem id="miHome" label="Home" width="120px"></menuitem>
<menu id="mnPrincipal" label="Principal" width="120px">
<menupopup id="mpPrincipal">
<menu id="mnTabela" label="Tabela">
<menupopup id="mpTabela">
<menuitem id="miCid" label="CID"></menuitem>
<menuitem id="miCbos" label="CBOS"></menuitem>
<menuitem label="Especialidade"></menuitem>
</menupopup>
</menu>
First define the data structure in your database.
this zul code:
<menubar>
<menuitem id="miHome" label="Home" width="120px"></menuitem>
<menu id="mnPrincipal" label="Principal" width="120px">
<menupopup id="mpPrincipal">
<menu id="mnTabela" label="Tabela">
<menupopup id="mpTabela">
<menuitem id="miCid" label="CID"></menuitem>
<menuitem id="miCbos" label="CBOS"></menuitem>
<menuitem label="Especialidade"></menuitem>
</menupopup>
</menu>
</menupopup>
</menu>
</menubar>
can be rewrite to java as :
Menubar mb = new Menubar();
Menuitem mi = new Menuitem("Home");
mi.setId("miHome");
mi.setWidth("120px");
mi.setParent(mb);
Menu mnu = new Menu("Principal");
mnu.setId("mnPrincipal");
mnu.setWidth("120px");
mnu.setParent(mb);
Menupopup mp = new Menupopup();
mp.setId("mpPrincipal");
mp.setParent(mnu);
mnu = new Menu("Tabela");
mnu.setId("mnTabela");
mnu.setParent(mp);
mp = new Menupopup();
mp.setId("mpTabela");
mp.setParent(mnu);
mi = new Menuitem("CID");
mi.setId("miCid");
mi.setParent(mp);
mi = new Menuitem("CBOS");
mi.setId("miCbos");
mi.setParent(mp);
mi = new Menuitem("Especialidade");
mi.setParent(mp);
I do not test this code but I think this could be give you some ideas...
