knockout JS bind to properties of object

I have a need to bind some HTML to an object, but my issue is that I don't know the properties of the object at development time.

I have a selectedItem property in my main view model which I have bound to a section in my HTML:

<div data-bind="with: selectedItem">

</div>

Now I want to generate a table based on the property name and property values:

<div data-bind="foreach: [WHAT DO I PUT HERE?]">
    <label class="control-label"><span data-bind="text: [OR HERE?]" /></label>
</div>

I have really no idea how to do this. Any help is greatly appreciated.

Also, just slightly extending this, I would like to handle the properties of the bound object differently, such as, if the property is just a primitive type, just output it, but if its another object/array, then handle it specially.

Can this be done?
