Hello @Pandra,
I'm not sure if you want to hide parts of your form or SharePoint elements located outside of your form. Can you please take a screenshot of your form and highlight the areas you want to conditionally hide?
Hello Nikitat
Not able to share a screenshot, but let's not focus on hiding the left navigation. We can address that separately. If you can assist with conditionally hiding just the EDIT and CLOSE buttons (and keeping the PDF icon available) based on the value of a Y/N field, that would be great. thanks!
