Idspace just like a Div but implements the ID space, all descendant components of Idspace (including the Idspace itself) form an independent ID space. Thus, you could use a idspace as the topmost component to group components. This way developers only need to maintain the uniqueness of each subset separately.
To group components without render a Div,
Idspace provides "nodom" mold. It would render no-dom widget in client-side. It only render comment nodes for positioning.
Notice that it's not recommended to use hflex/vflex in the children of nodom element.
<idspace> <window border="normal"> <button id="btn" label="button" /> </window> <div> <button id="btn" label="button" /> </div> </idspace>
