If you are new to formstrap, it is recommended that you read Getting Started > Field Basics first.
Floating Labels
The Floating Label is a feature of Bootstrap which causes the field label to "float" inside the input box rather than being positioned above it.
See the difference:
On a floating label input, when the input has focus the label animates out of the way. Try it (the examples above are working fields).
If the field type results in a picker being displayed inside the input then the label starts out of the way of the picker. See this date field.
Using Floating Labels
To make a field use a floating label, simply tick the box on the field metadata form. It is in the section called Boolean Attributes. Watch the video.
Restrictions
Bootstrap 5.3 supports floating labels on input-groups but this has not yet been implemented in formstrap.
Floating Labels don't honour the Bootstrap input size attribute - so on formstrap floating labels are only available on regular sized inputs and selects, and textarea (multi-line inputs).
