Use a custom state on the page “reveal Dispute inputs which is a yes or no” data type, add a condition to each Dispute input which says "reveal dispute inputs = yes, then in properties set this element is visible, now be sure the input is not visible on page load, you can also apply this same concept to a group, by grouping these dispute inputs into a group and add the same condition.
The final step is to say in workflow section when input dispute’s value is changed, now add an action set the state of reveal dispute inputs = yes,
you can add a toggle here too when reveal dispute inputs is yes set it to no when reveal inputs is no set it to yes,
Also on the page you can set the state value to default = no, reveal dispute inputs = no
hope that helps
