@Aarush_Kumar

You need to follow documentation for adding visible component because all visible components have thair own mock component for designer preview.

Also you need to add visible = true argument into @DesignerComponet annotation which you have not added.

@Aarush_Kumar
as I said in my previous post, mock is a simple java class that represents particular visible components into designer preview.

Let us tack an example of the button...

when you drag a button into a designer you will see a button into designer something like that. and also visible properties like height width change on the mock component according to your change into the designer property.

so how to make a mockup and where to place it @preetvadaliya

I would strongly recommend that you read section 4 of the "How to add a component" documentation.
