set selected option on select option binding

[Ricky]

Hi

I have : 

<select id="selectEnv" class="form-control input-sm" data-bind="foreach: availableEnvironments" onchange="main.changeEnvironment()">

   <option data-bind="text: name, value: id, disable: disabledEnvironment, css: unreachableCSS"/>

</select>                    

I have a property string set to "selected" or "".

Where can i put this property ?

There is no : 

- selected: isSelected

- attr {selected: isSelected }

Thx in advance

No one know ?? 

I just need to set "selected" property to 1 item

The documentation is totally wrong

No, it's perfectly correct, but you're not using the built-in concepts.

Maybe what you need is the prop binding, found here:

You should use the value binding to select an item:

<select id="selectEnv" class="form-control input-sm" data-bind="foreach: availableEnvironments, value: selectedItem" onchange="main.changeEnvironment()">

  <option data-bind="text: name, value: id, disable: disabledEnvironment, css: unreachableCSS"/>

</select>
