How to change grid default status in a ZK theme? - zk

Question

I have a page built with ZK. In this page there is a button that start a search. If there are some data them appear in a grid view.
Every data are built in this way:
v Date1 (dd/mm/yyyy)
- item
- item
- item
v Date2 (dd/mm/yyyy)
- item
- item
Lecter V means an arrow but I can't post an image so I use a "v" that have similar image to undestand.
It works correctely but there is a problem.
I would have this situation:
Date1 (dd/mm/yyyy)
Date2 (dd/mm/yyyy)
When I click on a date I want that the arrow became "v" and all data appear.
If in the first case I click on date it became close.
How to change the default view of grid items?
This is my code
<grid id="demoGrid" width="50%" height="400px" style ="float:left"
model="#bind(vm.value)" emptyMessage="No data">
<columns menupopup="auto">
<column sort="auto(Hour)" label="Hour" width="150px"/>
<column sort="auto(Value)" label="Value(bpm)" hflex="1" />
</columns>
<!-- template for group -->
<template name="model:group">
<group label="#load(each)" />
</template>
<!-- template for each element in model -->
<template name="model" >
<row>
<label value="#load(each.hour)" />
<label value="#load(each.value)" />
</row>
</template>
<!-- template for footer -->
<template name="model:groupfoot">
<groupfoot>
<cell colspan="5" style="text-align: right; padding-right: 15px">
<label value="#load(each)" style="font-weight:bold;" />
</cell>
</groupfoot>
</template>
</grid>
I try to use tag details in this subcode:
<template name="model">
<details open="false">
<row>
<label value="#load(each.hour)" />
<label value="#load(each.value)" />
</row>
</details>
</template>

Answer 1

Try the details like this :
<template name="model">
<row>
<detail open="false">
<hlayout>
<label value="#load(each.hour)" />
<label value="#load(each.value)" />
</hlayout>
</detail>
<label value="second column"/>
</row>
</template>
Explication :
Detail can have only 1 root element so that's why we set the the hlayout.
Of course you can change this to div or whatever you want.
The row tag has to be outside the detail tag.
The detail take a column so for this example you need to provide 2 columns.
Edit :
I created a fiddle.
