    Hi all,

    Interesting problem I have.

    if I use these versions

    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
    <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>

    "collapse in" class (default shown and than toggle to hide) works.

    But if I use these versions (default in bootstrap's web site now) collapse <g class="gr_ gr_7 gr-alert gr_spell gr_inline_cards gr_run_anim ContextualSpelling ins-del" id="7" data-gr-id="7">in</g> doesn't work,

    <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.2.1/css/bootstrap.min.css" integrity="sha384-GJzZqFGwb1QTTN6wy59ffF1BuGJpLSa9DkKMp0DgiMDm4iYMj70gZWKYbI706tWS" crossorigin="anonymous">

<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.6/umd/popper.min.js" integrity="sha384-wHAiFfRlMFy6i5SRaxvfOCifBUQy1xHdJ/yoi7FRNXMRBu5WHdZYu1hA6ZOblgut" crossorigin="anonymous"></script>

    Do you have any idea what can cause this and how can I solve this problem?

    Use "show" not "in". This is covered in the docs linked above.

        <div class="collapse show" id="collapseExample">
        <div class="card card-body">
            Anim pariatur cliche reprehenderit, enim eiusmod high life accusamus terry richardson ad squid. Nihil anim keffiyeh helvetica, craft beer labore wes anderson cred nesciunt sapiente ea proident.
        </div>
    </div>

    Or using JavaScript.

    Keep in mind that when asking for help on the forum it's always best to provide the source code, steps to reproduce the issue, expected outcome, and actual outcome.  Otherwise we have to guess what you're doing.

    Bootstrap 4 is a little different than 3 but in this case both HTML formats work in 4.  The recommended HTML format can be found here...

    https://getbootstrap.com/docs/4.0/components/collapse/

    Is there anyway you can post code that reproduces the issue?  I'm unable to reproduce the issue using the Bootstrap 4 template in ASP.NET Core 2.2 or using CDNs.

    Hi,

    the code you sent also has the same problem. Please use it <g class="gr_ gr_107 gr-alert gr_gramm gr_inline_cards gr_run_anim Style multiReplace" id="107" data-gr-id="107">as </g>

     <div class="collapse in"

    <g class="gr_ gr_107 gr-alert gr_gramm gr_inline_cards gr_disable_anim_appear Style multiReplace" id="107" data-gr-id="107">you</g> will see that it comes collapsed. but with "in" tag it should be shown as first placed not <g class="gr_ gr_214 gr-alert gr_spell gr_inline_cards gr_run_anim ContextualSpelling ins-del multiReplace" id="214" data-gr-id="214">hiden</g>.
