How to use the scaffolded LoginModel in another view than Login.cshtml? - asp.net-mvc

Question

I created a dropdown menu to log in instead of logging in at Login.cshtml but i can't seem to be able to use the model that contains the email password etc. I am not sure how to explain this but here is what i made so far:
I created the dropdown form and placed it in _LoginPartial.cshtml so it shows on the navbar
<div class="dropdown">
<button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
Log-In
</button>
<div class="dropdown-menu" aria-labelledby="dropdownMenuButton" style="width: 300px" >
<!----------->
<div class="col-lg-12">
<div class="text-center">
<h3><b>Log In</b></h3></div>
<form id="ajax-login-form" method="post" role="form" autocomplete="off">
<div class="form-group">
<label for="username">Username</label>
<input type="text" name="username" id="username" tabindex="1" class="form-control" placeholder="Username" value="" autocomplete="off">
</div>
<div class="form-group">
<label for="password">Password</label>
<input type="password" name="password" id="password" tabindex="2" class="form-control" placeholder="Password" autocomplete="off">
</div>
<div class="form-group">
<div class="col-xs-5">
<input type="submit" name="login-submit" id="login-submit" tabindex="4" class="form-control btn btn-danger" value="Log In">
</div>
</div>
<div class="col-xs-5" align="Center">
<input type="checkbox" tabindex="3" name="remember" id="remember">
<label for="remember"> Remember Me</label>
</div>
<div class="form-group">
<div class="row">
<div class="col-lg-12">
<div class="text-center">
<a tabindex="5" class="forgot-password">Forgot Password?</a>
</div>
</div>
</div>
</div>
</form>
</div>
and after this, i thought i can easily just insert #model loginmodel and i can start using that model but i'm met with so many errors. Any advice on how to do this? I am also open to other approaches too
