Checkbox

Hi,

I would create a checkbox field (for posts) with the possibility to select one or more colors (choices),
for example red, yellow, green, etc…

Both in backend and in frontend I would display only the values as circles.

Then, I would like that these choices/values could be linkable and searchable.
I mean, in the frontend, clicking any of these colors/circles, WP return all post with this value.

Thank you
