Answered MODX - Template Variable for Particular Page

I have one MainTemplate shared with pages like : home,about-us,contact-us

I also have template variable to control all pages' : meta description, og title, og image, og desc

I created a Template Variable Home Page Banner link to my MainTemplate to upload images just for Home Page, but when i click other resources, this Home Page Banner Template Variable will show up also.

Any method that makes Home Page Banner TV shows up only on home resources?

Is it duplicate another template from MainTemplate named as HomeTemplate for Home Page Banner TV only?

Personally I felt this way is abit dangerous for future maintanance.

May I know any more method to achieve this?

Tq.

you can also use a main-chunk, which holds the whole template-code and inject different placeholders to the main-chunk from the different templates.
