Why django forms shows input in column instead of a row - django

Question

I wonder why django modelForm shows input in a column instead of a row like this:
I like all input in my model to be in a row when putting {{ form|crispy}} in the template, as you can see in the template, even if add col-md-3 to resize the input in a row it does not work, I think there is something I need to know about django-forms.
template:
--- Bootstrap-5
<div class="container">
<div class="row justify-content-center">
<div class="col-md-3">
<form method="post" enctype="multipart/form-data">
{% csrf_token %}
{{ form|crispy}}
<button type="submit" class="btn btn-primary">Create Student</button>
</form>
</div>
</div>
</div>
The Result:
My Forms.py file:
class PrimaryForms(forms.ModelForm):
signature_of_student = JSignatureField(
widget=JSignatureWidget(
jsignature_attrs={'color':'#e0b642', 'height':'200px'}
)
)
signature_of_guardian = JSignatureField(
widget=JSignatureWidget(
jsignature_attrs={'color':'#e0b642', 'height':'200px'}
)
)
date_of_birth = forms.DateField(widget=forms.DateInput(attrs={'type': 'date'}))
class Meta:
model = Primary
fields = ['admission_number', 'profile_picture', 'first_name',
'last_name', 'gender', 'address_of_student', 'class_Of_student',
'comment_of_student', 'year_of_graduation', 'date_of_birth', 'religion', 'mother_name',]
How can I make my input to be in rows?
