Creating Dropdown list in QGIS Print Composer

Question

I ́m trying to find a way to create a dropdown list in the QGIS Print composer. I know that there ́s a way to do it in the attributes tables but what I ́m looking for is to have the same result in the print composer itens. For more info about the dropdown list I ́ve separated this link:

During my search I saw many pages like this:

2 - Creating multiple select dropdown list in QGIS

3 - Creating a dropdown list to select by different attributes in QGIS

4 - https://youtu.be/CVhBMWReYZM

I ́m expecting to see this in the print composer instead of Canvas:

How can I create the dropdown list? I ́m using QGIS version 3.18
