Is it possible to add an information icon (or something similar) to the field's name of a form with a mouse over event that displays a tooltip with some info? We have a requirement to display a text to explain the meaning of some fields.
You can add a field description in filed settings. The description will be displayed under the input.
Or you can change the tooltip text of the input. Please see the code sample below.
fd.spRendered(function() {
var singleLine = $(fd.field('Title').$el).find('input');
$(singleLine).attr('title', 'This is Title field, input Title, please!');
});
