HELP: Conditional & multiplel Hide/Show Elements on click in webflow

Hello
Please take a look at the preview file. There’s pricing table and in those tables., there are plan comparision like design & drawing, strcuture etc…
on click of any comparision category every 4 table’s category should Open up.
For now I did this interaction by targeting every element on click. Problem with this approach is when I click on any category I also have to show hyphen icon and hide the plus icon. This only happens on just first category I’ve clicked on. The other category has content open but shows the plus icon instead on hyphen.

How can I resolve this issue?
Thanks
