This requires the help of special electronic menu software, and ordinary picture display applications should not be enough, because it involves the operation of ordering something. As far as I know, the electronic cookbooks for displaying meals are good. There is an iPad version, you can freely design your own recipe page style, and it is also very simple to use. You only need to input data in a simple excel way, and then set dishes pictures in excel. Very simple and easy to use, easy to maintain, just update the excel file.
