Bootstrap 5 collapse wont revert on second Button click-CodePudding

I have a Button which shows a div on Button Click using Boostrap 5 Class "Collapse". It actually shows the div on the first click, but the content wont hide again when the User clicks the Button a second time.

<div >
   
    <button role="button"  data-bs-toggle="collapse" data-bs-target="#rrCollapse" >Hinzufügen</button>
    <div  id="rrCollapse">
        <div >
            <div >

                <h1>...</h1>
             
            </div>
        </div>
    </div>
</div>

This is the Button and the div which collapses after a click

    <link href="~/lib/bootstrap/dist/css/bootstrap.css" rel="stylesheet" />
    <link href="~/lib/bootstrap/dist/css/bootstrap.min.css" rel="stylesheet" />
    <script src="~/lib/jquery/dist/jquery.min.js"></script>
    <script src="~/lib/jquery/dist/jquery.js"></script>
    <script src="~/lib/bootstrap/dist/js/bootstrap.js"></script>
    <script src="~/lib/bootstrap/dist/js/bootstrap.bundle.min.js"></script>

All files I used.

I am working on ASP.net Core 6.0

CodePudding user response：

If you have used the default _Layout, and in the _Layout.cshtml there are the <link> and <scrpit> , you don't need to add these files to the view .

<link rel="stylesheet" href="~/lib/bootstrap/dist/css/bootstrap.min.css" />
<script src="~/lib/jquery/dist/jquery.min.js"></script>
<script src="~/lib/bootstrap/dist/js/bootstrap.bundle.min.js"></script>

result:

Update:

In the view try below code:

@{
    Layout = null;
}



<link rel="stylesheet" href="~/lib/bootstrap/dist/css/bootstrap.min.css" />
<script src="~/lib/jquery/dist/jquery.min.js"></script>
<script src="~/lib/bootstrap/dist/js/bootstrap.bundle.min.js"></script>
<div >
   
    <button role="button"  data-bs-toggle="collapse" data-bs-target="#rrCollapse" >Hinzufügen</button>
    <div  id="rrCollapse">
        <div >
            <div >

                <h1>...</h1>
             
            </div>
        </div>
    </div>
</div>

This is my _Layout.cshtml, you can refer it to change your _layout.
