 * I want to use a url string in a submenu link to activate a checkbox on the landing
   page that by default is off. I’ve tried using the field_value=1 and slug=1, such
   as
    [https://domain.com/page?fld_12345=1](https://domain.com/page?fld_12345=1)
   or [https://domain.com/page?slug=1](https://domain.com/page?slug=1) as well as
   a few other options such as ?fld_12345_1=1 and ?fld_12345_opt4321=1 based on 
   various values in the CSS and nothing works.
 * How can I trigger a checkbox using a url string?
