How can I make text selectable with a long-press on iOS

Bezls act like apps, and default behavior on iOS is that app components cannot be copied. How do I override that?

You can add CSS to a bezl to make text selectable. This CSS segment should do the trick:

h3 {
-webkit-user-select: text;
-moz-user-select: text;
-ms-user-select: text;
user-select: text;
}

That would make it so that every h3 in a bezl would allow for a long-press event to allow for copy and paste. So this would then work in the bezl:

<h3>Hello</h3>

You could hold a click on Hello and the copy option would be available. Probably a better way is to put it in a class like .selectable and then you can apply that class to any element to allow it to support copy/paste.
