How to navigate openIn: 'popup' mode fullscreen?

          openIn : 'popup' // i want popup mode full screen for tablet or non tablet

You need to get the class: popup-tablet-fullscreen into the page so it is as follows:

<div class="popup-router-open-in popup modal-in popup-tablet-fullscreen"

openIn : ‘popup’ // default from f7, how to change mode full screen ?

I don’t see a setting or config to do it. What I gave you was a workaround. As soon as the popup is opened you need to add the class as shown and the popup will go full-screen on desktop/tablet. Ie send your own property that you want it fullscreen, add an event to the popup/page opened, detect your property and using F7 DOM add in the class.
