Environment:
Event Temple Web App
Procedure:
To remove pricing in the Menu Items Document element:
Click the edit icon on the element
Unselect the 'price' component (shown below)
Click Apply
Save your Document
If you would like the price hidden on all future BEO's you can follow the same steps on the relevant Document Template (or templates, if you have multiple) - once you've done that, next time you use the template it'll have the price hidden 😁
