masking overlay

Hello
Is there a way to mask a webix ui component to disable user interaction. Something like ‘http://docs-origin.sencha.com/extjs/5.0/apidocs/#!/api/Ext.dom.Element-method-mask’. I need a mask over a form to say ‘Loading…’ until the form values are completely loaded. This seems like a common pattern but I can’t find an example.

Thanks

try this code:
