Top menu bar and left hand side menu remain static, ASP.NET Core

I am using ASP.NET Core 6, jQuery and Bootstrap. I have a screen that has a left hand side menu, I wish the menu and top menu remain static and only the input details can scroll vertically.

See this screenshot:

My _layout markup:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />

My patient navigation, the left hand side menu:

<div class="col-md-3">
    <div id="designationReports">
        <ul class="nav nav-pills flex-column">
            <li class="nav-item"><a class="nav-link" id="Designated" asp-controller="Patient" asp-action="Edit">Patient Demographic Information</a></li>
            <li class="nav-item"><a class="nav-link" id="DesignationRenewalDue" asp-controller="Personal" asp-action="History">Personal History</a></li>
        </ul>
    </div>
</div>

This is my patient layout file:

@{
    Layout = "_Layout";
}

<h4>Patient</h4>
<hr />
<div>
    <div class="row">
        <div class="col-md-3">
            @await Html.PartialAsync("_PatientNav")
        </div>

        @RenderBody()
    </div>
</div>

An extract of my patient.cshtml:

@{
    Layout = "_LayoutPatient";
}

@{
    await Html.RenderPartialAsync("_Patient");
}

And my patient details file (_Patient.cshtml):

<div class="card-body">
    <fieldset class="form-group">
        <div class="form-row">
            <div class="col-md-7">

                    </div>
                </div>

                <div class="row">

                    </div>
                </div>
                <div class="row">
                    <label class="control-label col-md-3">Specify:</label>

                    <div class="col-md-8 mb-2">

                        <span class="text-danger"></span>
                    </div>
                </div>

                <div class="row">
                    <label class="control-label col-md-3">Gender:</label>

                    <div class="col-md-8 mb-2">
                        <select style=" width: 363px; height: 37px;"></select>
                        <span class="text-danger"></span>
                    </div>
                </div>
            </div>
    </fieldset>
</div>

I tried something like the below for the left hand menu, didn't work -

<div class="container-fluid">
    <div class="row flex-nowrap">
        <div class="col-auto col-md-3 col-xl-2 px-sm-2 px-0 bg-dark">
            <div class="d-flex flex-column align-items-center align-items-sm-start px-3 pt-2 text-white min-vh-100">

Didn't really work.

Any help would be greatly appreciated.

Solution

  • You can use the Flexbox layout on the .row element, and then use the overflow-y attribute on the input details container, like this:

     <div>
    <h4>Patient</h4>
    <hr />
    <div class=".row d-flex">
        <div class="col-md-2" >
            @await Html.PartialAsync("_PatientNav")
        </div>
        <div class="col-md-8" id="FixH">
            @RenderBody()
        </div>
    </div>
</div>


   <style>
    #FixH {
        overflow-y: auto;
        max-height: 400px;
        width: 80%;
    }
   </style>
