formGroupElementContainerMarker

Marker CSS class name for all container elements of a single formControl rendering. The ControlRenderer implementation must apply this to all container elements until the base level, where the label and the control itself are exposed.

This ensures that the label and the rest of the control fit into a 2 column grid if the label is placed left hand side.

For example:

<div class="formGroupElementContainerMarker"> // must be excluded from layout
    <fieldset class="formGroupElementContainerMarker"> // must be excluded from layout
        <label></label>
        <div>
            <input ...></input>
            <!-- Helpertext -->
            <!-- Errormessages -->
        </div>
    </fieldset>
</div>
