I've created a custom PowerApps form for a SharePoint list. When I click on New or edit, the form shows the toolbar at the top with Save/Cancel,Copy Link/Customize options. I would like to hide this menu as I'm managing the save through a button control in the form. Is it possible to hide this menu? It appears the menu is being added by SharePoint than PowerApps. Is it possible to add CSS through PowerApps and hide the menu through CSS?
Based on what you are wanting to do I would suggest creating a stand-alone PowerApp that connects to your SharePoint list rather than using the "Customize Form" option like you have. The reason being, when you to a stand-alone app, you have much more control over the interface and you can create your own Save/Cancel buttons.
Thanks for the reply. If I create stand alone app, I dont get the ability to launch the form on clicking of New button from SharePoint. Also I've almost finished developing the form and would be a lot of work unless I can import the existing app.
