I have a form with the following code:
<form action="" name="formulario" id="formulario" method="POST">
<div class="row">
<div class="form-group col-md-6">
<label for="">Tipo usuario(*):</label>
<select name="idtipousuario" id="idtipousuario" class="form-control selectpicker" required>
</select>
</div>
</div>
</form>
The problem is that it is shown twice, with dropdown before the Select, I am convinced that it is some load of the Select CSS that in theory cancels the dropdown but I have tried everything and I don't know where to go anymore, I am working with adminLTE. Does something happen to you?
Thank you all for the suggestions, in the end I solved it by importing the CSS and JS CDNs from the Bootstrap 4.6.1 version and replacing them with the ones that adminlte brings. I need to do some tweaking in the dropdown but it is already displayed correctly and Bootstrap's own CSS cancels the duplicate dropdown that I got...
