Here when input fields are filled with data the placeholder returning to the same place even after entering the required fields ! What the code should do -> the placeholder should not come back to the normal place when the input fields are Entered !
Try adding data-mdb-input-init attribute to each form-outline (also, it creates a border on input):
example:
<div class="form-outline" data-mdb-input-init>
<input type="text" id="form3Example1" class="form-control" />
<label class="form-label" for="form3Example1">First name</label>
</div>>
