Panel may be moveable but prevent move, remove properties on the childs

How can I prevent move, remove properties on the childs?
In this case (see code below) the user may move the parent (Template_2), but all the childs may not move. 

I tried it with '**propagate**', but these properties are applicable to the parent too. 
I need an option too aply properties specifically on childs.

`blockManager.add('Template_2', {
label: 'Template 2',
content: 'lorem ipsem',
});
const domc = editor.DomComponents;
const defaultType = domc.getType('default');
const defaultModel = defaultType.model;
const defaultView = defaultType.view;

domc.addType('Template_2', {
    model: defaultModel.extend(
	{
		defaults: Object.assign({}, defaultModel.prototype.defaults, 
		{
			// True if the component is removable from the canvas
			removable: true,
			
			// Indicates if it's possible to drag the component inside other
			// Tip: Indicate an array of selectors where it could be dropped inside
			draggable: true,
			
			// Indicates if it's possible to drop other components inside
			// Tip: Indicate an array of selectors which could be dropped inside
			droppable: true,
			
			// Set false if don't want to see the badge (with the name) over the component
			badgable: true,
			
			// True if it's possible to style it
			// Tip:  Indicate an array of CSS properties which is possible to style
			stylable: true,
			
			// Highlightable with 'dotted' style if true
			highlightable: true,
			
			// True if it's possible to clone the component
			copyable: true,
			
			// Indicates if it's possible to resize the component (at the moment implemented only on Image Components)
			resizable: false,
			
			// Allow to edit the content of the component (used on Text components)
			editable: true,
			
			propagate: ['removable','draggable','droppable','editable',]
		}),
	},
	{
		isComponent: function (el)
		{
			
			if (el.tagName == 'DIV')
			{
				return {type: 'Template_2'};
			}
		},
	}),
	view: defaultView,
});`
