Issue Expanding Home Loan Calculator Dropdown

[wrightman-henry]

Hello! Huge fan of your calculators - i'm trying to leverage the home loan calculator on my word press site but unfortunately clicking on the dropdown doesn't do anything. Weirdly enough, if I adjust the CSS on the component to remove max-height:0, the dropdown shows the additional content, but the "toggle" button / dropdown still seems disabled. Not really sure what is going on - possible collisions with other javascript sources? Or perhaps need to delete other plugins?

Thanks!
