[QUESTION] Add Dropdown to block using Traits

Hi @artf ,

I hope that you are well,

I was wondering whether you could help me with some simple issue that I am having (I have recently started using GrapeJS.

Issue: using a plugin create a block and within the traits section have a drop down that changes the type of block displayed.

Here is my current plugin code which displays two blocks:

function myPlugin(editor){


  editor.BlockManager.add('my-first-block', {
    label: 'Simple block',
    content: '<div class="my-block">This is a simple block</div>',
    category: 'Apple'


  })

  editor.BlockManager.add('my-second-block', {
    label: 'second block',
    content: '<div class="my-block">This is a simple block</div>',
    category: 'Apple'

    
  });
}

I would like a dropdown to appear in the settings (traits) tab where I can select other options for content e.g:

Simple Block ------------> Red ------------> Orange ------------> Yellow

And then change the content accordingly as follows:

Red: content: '<div class="my-block">This is a simple red block</div>', Orange: content: '<div class="my-block">This is a simple orange block</div>', Yellow: content: '<div class="my-block">This is a simple yellow block</div>', Kind Regards Aiyush
