Hello @eweiler,
You can use this code to adjust the height of the rich text input to the content.
fd.spRendered(function() {
//Replace RichText with the internal name of the field
fd.field('RichText').ready().then(function(field) {
var editor = $(field.$el).find('.k-editor');
function recalcHeight() {
var actualHeight = Math.round(editor.height());
var conetntHeight = field.widget.document.body.scrollHeight;
var newHeight = (conetntHeight > actualHeight) ? conetntHeight + 100 : actualHeight;
editor.height(newHeight);
}
recalcHeight();
setInterval(function(){ recalcHeight(); }, 1000);
});
});
