Custom template for each selected item using ng-label-tmp

Is your feature request related to a problem? Please describe.
I'm always frustrated when I can't customize the appearance of each selected item in my dropdown menu. Currently, I'm limited to a plain text with image or text with checkbox representation, which doesn't provide enough visual context or interactivity. For example, I want to include images, values, and checkboxes within the dropdown selections to improve user experience and make the selections more informative and engaging.

Describe the solution you'd like
I would like to have the ability to use ng-option-tmp to define custom templates for each selected item in the dropdown. This template should support embedding an image, displaying a specific value (ng-value), and including a checkbox for each item. The custom template should be flexible and easy to define, allowing for a combination of HTML and Angular expressions.

Describe alternatives you've considered
It must have input checkbox inside the ng-option-tmp.
