How can I check the value of a dropdown menu in craft cms / twig?

Question

I have a dropdown menu with 2 options

• Ordered
• Unordered

I want to check if the value is Unordered or Ordered

  {% set viewModel = {
     cards: content['cards'] ?? [],
     cardListType: content.cardListType ?? ''
   } %}


   {{ viewModel.cardListType|json_encode() }}

Returns this to me {"0":{"label":"Unordered","value":"unordered","selected":true}}

I want to check if the value of viewModel.cardListType is unordered and that it's selected.

I have tried

   {% if viewModel.cardListType.value is unordered %}
         <p>UNORDERED</p>
   {% endif %}

and

  {% if viewModel.cardListType.value:unordered %}
         <p>UNORDERED</p>
   {% endif %}

and several other variations of this. I don't understand the documentation/ syntax for dropdowns in craft or twig. Can someone please explain like I'm 5 how this works and how to check the value? I am using Craft 3 if this changes the syntax

Thanks in advance
