'Required' Option In Capacitor App

Wonder if somebody could help. I am using capacitor, SQLite and bootstrap for a mobile app. I have a form and have selected the ‘required’ option. This seems to make no difference and will let it be submitted as a blank value. I am using a page flow to submit the data as shown on Using Local Databases in Mobile and Desktop apps.

Anybody any ideas were I’m going wrong?

Have you set the form type to server connect? In the form properties panel click convert to and select server connect.

Cheers, I haven’t at the moment. Not sure if I can do this though as I am not using it as a server connect form? Using the page flow to save to Sqlite.
